+All error responses include an `error` object with `code` and `message` fields.
+
+### Pagination
+List endpoints support pagination with `page` and `page_size` parameters.
+Default page size is 20, maximum is 100.
+
+### Filtering
+Range filters use `{field}_min` and `{field}_max` naming convention.
+Search uses the `search` parameter.
+Ordering uses the `ordering` parameter (prefix with `-` for descending).
+
+### Field Naming
+All field names use snake_case convention (e.g., `image_url`, `created_at`).

+
+## Template Inheritance
+
+### Base Template
+
+All pages extend `base/base.html`. Available blocks:
+
+```django
+{% extends "base/base.html" %}
+
+{# Page title (appears in <title> and meta tags) #}
+{% block title %}My Page - ThrillWiki{% endblock %}
+
+{# Main page content #}
+{% block content %}
+    <h1>Page Content</h1>
+{% endblock %}
+
+{# Additional CSS/meta in <head> #}
+{% block extra_head %}
+    <link rel="stylesheet" href="...">
+{% endblock %}
+
+{# Additional JavaScript before </body> #}
+{% block extra_js %}
+    <script src="..."></script>
+{% endblock %}
+
+{# Additional body classes #}
+{% block body_class %}custom-page{% endblock %}
+
+{# Additional main element classes #}
+{% block main_class %}no-padding{% endblock %}
+
+{# Override navigation (defaults to enhanced_header.html) #}
+{% block navigation %}{% endblock %}
+
+{# Override footer #}
+{% block footer %}{% endblock %}
+
+{# Meta tags for SEO #}
+{% block meta_description %}Page description{% endblock %}
+{% block og_title %}Open Graph title{% endblock %}
+{% block og_description %}Open Graph description{% endblock %}
+```
+
+### Inheritance Example
+
+```django
+{% extends "base/base.html" %}
+{% load static %}
+{% load park_tags %}
+
+{% block title %}{{ park.name }} - ThrillWiki{% endblock %}
+
+{% block extra_head %}
+<link rel="stylesheet" href="{% static 'css/park-detail.css' %}">
+{% endblock %}
+
+{% block content %}
+<div class="container">
+    <h1>{{ park.name }}</h1>
+    {% include "parks/partials/park_header_badge.html" %}
+</div>
+{% endblock %}
+
+{% block extra_js %}
+<script src="{% static 'js/park-map.js' %}"></script>
+{% endblock %}
+```
+
+## Component Usage
+
+### Pagination
+
+```django
+{# Standard pagination #}
+{% include 'components/pagination.html' with page_obj=page_obj %}
+
+{# HTMX-enabled pagination #}
+{% include 'components/pagination.html' with page_obj=page_obj use_htmx=True hx_target='#results' %}
+
+{# Small size #}
+{% include 'components/pagination.html' with page_obj=page_obj size='sm' %}
+```
+
+### Status Badge
+
+```django
+{# Basic badge #}
+{% include 'components/status_badge.html' with status=park.status %}
+
+{# Interactive badge with HTMX refresh #}
+{% include 'components/status_badge.html' with
+    status=park.status
+    badge_id='park-header-badge'
+    refresh_trigger='park-status-changed'
+    scroll_target='park-status-section'
+    can_edit=perms.parks.change_park
+%}
+```
+
+### Stats Card
+
+```django
+{# Basic stat #}
+{% include 'components/stats_card.html' with label='Total Rides' value=park.ride_count %}
+
+{# Clickable stat #}
+{% include 'components/stats_card.html' with label='Total Rides' value=42 link=rides_url %}
+
+{# Priority stat (highlighted) #}
+{% include 'components/stats_card.html' with label='Operator' value=park.operator.name priority=True %}
+```
+
+### History Panel
+
+```django
+{# Basic history #}
+{% include 'components/history_panel.html' with history=history %}
+
+{# With FSM toggle for moderators #}
+{% include 'components/history_panel.html' with
+    history=history
+    show_fsm_toggle=True
+    fsm_history_url=fsm_url
+    model_type='park'
+    object_id=park.id
+    can_view_fsm=perms.parks.change_park
+%}
+```
+
+### Loading Indicator
+
+```django
+{# Block indicator #}
+{% include 'htmx/components/loading_indicator.html' with id='loading' message='Loading...' %}
+
+{# Inline indicator (in buttons) #}
+{% include 'htmx/components/loading_indicator.html' with id='btn-loading' inline=True size='sm' %}
+
+{# Overlay indicator #}
+{% include 'htmx/components/loading_indicator.html' with id='overlay' mode='overlay' %}
+```
+
+## Form Rendering
+
+### Form Layouts
+
+```django
+{# Stacked layout (default) #}
+{% include 'forms/layouts/stacked.html' with form=form %}
+
+{# Inline/horizontal layout #}
+{% include 'forms/layouts/inline.html' with form=form %}
+
+{# 2-column grid #}
+{% include 'forms/layouts/grid.html' with form=form cols=2 %}
+
+{# With excluded fields #}
+{% include 'forms/layouts/stacked.html' with form=form exclude='password2' %}
+
+{# Custom submit text #}
+{% include 'forms/layouts/stacked.html' with form=form submit_text='Save Changes' %}
+```
+
+### Individual Fields
+
+```django
+{# Standard field #}
+{% include 'forms/partials/form_field.html' with field=form.email %}
+
+{# Field with custom label #}
+{% include 'forms/partials/form_field.html' with field=form.email label='Email Address' %}
+
+{# Field with HTMX validation #}
+{% include 'forms/partials/form_field.html' with
+    field=form.username
+    hx_validate=True
+    hx_validate_url='/api/validate/username/'
+%}
+```
+
+## Template Tags
+
+### Loading Order
+
+Always load template tags in this order:
+
+```django
+{% load static %}
+{% load i18n %}
+{% load park_tags %}         {# App-specific #}
+{% load safe_html %}         {# Sanitization #}
+{% load common_filters %}    {# Utility filters #}
+{% load cache %}             {# Caching (if used) #}
+```
+
+### Available Filters
+
+**common_filters:**
+```django
+{{ datetime|humanize_timedelta }}  {# "2 hours ago" #}
+{{ text|truncate_smart:50 }}       {# Truncate at word boundary #}
+{{ number|format_number }}         {# "1,234,567" #}
+{{ number|format_compact }}        {# "1.2K", "3.4M" #}
+{{ dict|get_item:"key" }}          {# Safe dict access #}
+{{ count|pluralize_custom:"item,items" }}
+{{ field|add_class:"form-control" }}
+```
+
+**safe_html:**
+```django
+{{ content|sanitize }}        {# Full HTML sanitization #}
+{{ comment|sanitize_minimal }} {# Basic text only #}
+{{ text|strip_html }}         {# Remove all HTML #}
+{{ data|json_safe }}          {# Safe JSON for JS #}
+{% icon "check" class="w-4 h-4" %}  {# SVG icon #}
+```
+
+## Context Variables
+
+### Naming Conventions
+
+| Type | Convention | Example |
+|------|------------|---------|
+| Single object | Lowercase model name | `park`, `ride`, `user` |
+| List/QuerySet | `{model}_list` | `park_list`, `ride_list` |
+| Paginated | `page_obj` | Django standard |
+| Single form | `form` | Standard |
+| Multiple forms | `{purpose}_form` | `login_form`, `signup_form` |
+
+### Avoid
+
+- Generic names: `object`, `item`, `obj`, `data`
+- Abbreviated names: `p`, `r`, `f`, `frm`
+
+## HTMX Patterns
+
+See `htmx/README.md` for detailed HTMX documentation.
+
+### Quick Reference
+
+```django
+{# Swap strategies #}
+hx-swap="innerHTML"   {# Replace content inside #}
+hx-swap="outerHTML"   {# Replace entire element #}
+hx-swap="beforeend"   {# Append #}
+hx-swap="afterbegin"  {# Prepend #}
+
+{# Target naming #}
+hx-target="#park-123"        {# Specific object #}
+hx-target="#results"         {# Page section #}
+hx-target="this"             {# Self #}
+
+{# Event naming #}
+hx-trigger="park-status-changed from:body"
+hx-trigger="auth-changed from:body"
+```
+
+## Caching
+
+Use fragment caching for expensive template sections:
+
+```django
+{% load cache %}
+
+{# Cache navigation for 5 minutes per user #}
+{% cache 300 nav user.id %}
+    {% include 'components/layout/enhanced_header.html' %}
+{% endcache %}
+
+{# Cache stats with object version #}
+{% cache 600 park_stats park.id park.updated_at %}
+    {% include 'parks/partials/park_stats.html' %}
+{% endcache %}
+```
+
+### Cache Keys
+
+Include in cache key:
+- User ID for personalized content
+- Object ID for object-specific content
+- `updated_at` for automatic invalidation
+
+Do NOT cache:
+- User-specific actions (edit buttons)
+- Form CSRF tokens
+- Real-time data
+
+## Accessibility
+
+### Checklist
+
+- [ ] Single `<h1>` per page
+- [ ] Heading hierarchy (h1 → h2 → h3)
+- [ ] Labels for all form inputs
+- [ ] `aria-label` for icon-only buttons
+- [ ] `aria-describedby` for help text
+- [ ] `aria-invalid` for fields with errors
+- [ ] `role="alert"` for error messages
+- [ ] `aria-live` for dynamic content
+
+### Skip Links
+
+Base template includes skip link to main content:
+```html
+<a href="#main-content" class="sr-only focus:not-sr-only ...">
+    Skip to main content
+</a>
+```
+
+### Landmarks
+
+```html
+<nav role="navigation" aria-label="Main navigation">
+<main role="main" aria-label="Main content">
+<footer role="contentinfo">
+```
+
+## Security
+
+### Safe HTML Rendering
+
+```django
+{# User content - ALWAYS sanitize #}
+{{ user_description|sanitize }}
+
+{# Comments - minimal formatting #}
+{{ comment_text|sanitize_minimal }}
+
+{# Remove all HTML #}
+{{ raw_text|strip_html }}
+
+{# NEVER use |safe for user content #}
+{{ user_input|safe }}  {# DANGEROUS! #}
+```
+
+### JSON in Templates
+
+```django
+{# Safe JSON for JavaScript #}
+<script>
+    const data = {{ python_dict|json_safe }};
+</script>
+```
+
+## Component Documentation Template
+
+Each component should have a header comment:
+
+```django
+{% comment %}
+Component Name
+==============
+
+Brief description of what the component does.
+
+Purpose:
+    Detailed explanation of the component's purpose.
+
+Usage Examples:
+    {% include 'components/example.html' with param='value' %}
+
+Parameters:
+    - param1: Description (required/optional, default: value)
+    - param2: Description
+
+Dependencies:
+    - Alpine.js for interactivity
+    - HTMX for dynamic updates
+
+Security: Notes about sanitization, XSS prevention
+{% endcomment %}
+```
+
+## File Naming
+
+| Type | Pattern | Example |
+|------|---------|---------|
+| List view | `{model}_list.html` | `park_list.html` |
+| Detail view | `{model}_detail.html` | `park_detail.html` |
+| Form view | `{model}_form.html` | `park_form.html` |
+| Partial | `{model}_{purpose}.html` | `park_header_badge.html` |
+| Component | `{purpose}.html` | `pagination.html` |

+History Panel Component
+=======================
+
+A reusable history panel component for displaying object change history and FSM transitions.
+
+Purpose:
+    Displays both regular history records and FSM (Finite State Machine) transition
+    history for parks, rides, and other entities with historical tracking.
+
+Usage Examples:
+    Basic history:
+        {% include 'components/history_panel.html' with history=history %}
+
+    With FSM toggle (for moderators):
+        {% include 'components/history_panel.html' with history=history show_fsm_toggle=True fsm_history_url=fsm_url model_type='park' object_id=park.id can_view_fsm=perms.parks.change_park %}
+
+    Ride history:
+        {% include 'components/history_panel.html' with history=history show_fsm_toggle=True fsm_history_url=fsm_url model_type='ride' object_id=ride.id can_view_fsm=perms.rides.change_ride %}
+
+Parameters:
+    Required:
+    - history: QuerySet or list of history records
+
+    Optional (FSM):
+    - show_fsm_toggle: Show toggle button for FSM history (default: False)
+    - fsm_history_url: URL for loading FSM transition history via HTMX
+    - model_type: Model type for FSM history (e.g., 'park', 'ride')
+    - object_id: Object ID for FSM history
+    - can_view_fsm: Whether user can view FSM history (default: False)
+
+    Optional (styling):
+    - title: Panel title (default: 'History')
+    - panel_class: Additional CSS classes for panel
+    - max_height: Maximum height for scrollable area (default: 'max-h-96')
+    - collapsed: Start collapsed (default: False)
+
+Dependencies:
+    - Tailwind CSS for styling
+    - Alpine.js for interactivity
+    - HTMX (optional, for FSM history lazy loading)
+    - Font Awesome icons
+
+Accessibility:
+    - Uses heading structure for panel title
+    - Toggle button has accessible label
+    - History items use semantic structure
+{% endcomment %}

+
+    With subtitle:
+        {% include 'components/layout/page_header.html' with title='Cedar Point' subtitle='Sandusky, Ohio' %}
+
+    With icon:
+        {% include 'components/layout/page_header.html' with title='Parks' icon='fas fa-map-marker-alt' %}
+
+    With actions:
+        {% include 'components/layout/page_header.html' with title='Parks' %}
+            {% block page_header_actions %}
+                <a href="{% url 'parks:create' %}" class="btn btn-primary">
+                    <i class="fas fa-plus mr-2"></i>Add Park

+# Navigation Components
+
+This directory contains navigation-related template components.
+
+## Components
+
+### breadcrumbs.html
+
+Semantic breadcrumb navigation with Schema.org structured data support.
+
+#### Features
+
+- Accessible navigation with proper ARIA attributes
+- Schema.org BreadcrumbList JSON-LD for SEO
+- Responsive design with mobile-friendly collapse
+- Customizable separators and icons
+- Truncation for long labels
+
+#### Basic Usage
+
+```django
+{# Breadcrumbs are automatically included from context processor #}
+{% include 'components/navigation/breadcrumbs.html' %}
+```
+
+#### Setting Breadcrumbs in Views
+
+```python
+from apps.core.utils.breadcrumbs import build_breadcrumb, BreadcrumbBuilder
+from django.urls import reverse
+
+def park_detail(request, slug):
+    park = get_object_or_404(Park, slug=slug)
+
+    # Option 1: Build breadcrumbs manually
+    request.breadcrumbs = [
+        build_breadcrumb('Home', '/', icon='fas fa-home'),
+        build_breadcrumb('Parks', reverse('parks:list')),
+        build_breadcrumb(park.name, is_current=True),
+    ]
+
+    # Option 2: Use the builder pattern
+    request.breadcrumbs = (
+        BreadcrumbBuilder()
+        .add_home()
+        .add('Parks', reverse('parks:list'))
+        .add_current(park.name)
+        .build()
+    )
+
+    return render(request, 'parks/detail.html', {'park': park})
+```
+
+#### Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `items` | list | `breadcrumbs` | List of Breadcrumb objects |
+| `show_schema` | bool | `True` | Include Schema.org JSON-LD |
+| `show_home_icon` | bool | `True` | Show icon on home breadcrumb |
+| `separator` | str | chevron | Custom separator character |
+| `max_visible` | int | `3` | Max items before mobile collapse |
+| `container_class` | str | `""` | Additional CSS classes |
+
+#### Accessibility
+
+- Uses `<nav>` element with `aria-label="Breadcrumb"`
+- Ordered list (`<ol>`) for semantic structure
+- `aria-current="page"` on current page item
+- Hidden separators for screen readers
+
+#### Examples
+
+**Custom separator:**
+```django
+{% include 'components/navigation/breadcrumbs.html' with separator='/' %}
+```
+
+**Without Schema.org:**
+```django
+{% include 'components/navigation/breadcrumbs.html' with show_schema=False %}
+```
+
+**Custom breadcrumbs:**
+```django
+{% include 'components/navigation/breadcrumbs.html' with items=custom_crumbs %}
+```
+
+## Breadcrumb Utilities
+
+### BreadcrumbBuilder
+
+Fluent builder for constructing breadcrumbs:
+
+```python
+from apps.core.utils.breadcrumbs import BreadcrumbBuilder
+
+breadcrumbs = (
+    BreadcrumbBuilder()
+    .add_home()
+    .add_from_url('parks:list', 'Parks')
+    .add_model(park)
+    .add_from_url('rides:list', 'Rides', {'park_slug': park.slug})
+    .add_model_current(ride)
+    .build()
+)
+```
+
+### get_model_breadcrumb
+
+Generate breadcrumbs for model instances with parent relationships:
+
+```python
+from apps.core.utils.breadcrumbs import get_model_breadcrumb
+
+# For a Ride that belongs to a Park
+breadcrumbs = get_model_breadcrumb(
+    ride,
+    parent_attr='park',
+    list_url_name='rides:list',
+    list_label='Rides',
+)
+# Returns: [Home, Parks, Cedar Point, Rides, Millennium Force]

+Breadcrumb Navigation Component
+===============================
+
+Semantic breadcrumb navigation with Schema.org structured data support.
+
+Purpose:
+    Renders accessible breadcrumb navigation with proper ARIA attributes,
+    Schema.org BreadcrumbList markup, and responsive design.
+
+Usage Examples:
+    Basic usage (breadcrumbs from context processor):
+        {% include 'components/navigation/breadcrumbs.html' %}
+
+    Custom breadcrumbs:
+        {% include 'components/navigation/breadcrumbs.html' with items=custom_breadcrumbs %}
+
+    Without Schema.org markup:
+        {% include 'components/navigation/breadcrumbs.html' with show_schema=False %}
+
+    Custom separator:
+        {% include 'components/navigation/breadcrumbs.html' with separator='>' %}
+
+    Without home icon:
+        {% include 'components/navigation/breadcrumbs.html' with show_home_icon=False %}
+
+Parameters:
+    Optional:
+    - items: List of Breadcrumb objects (default: breadcrumbs from context)
+    - show_schema: Include Schema.org JSON-LD (default: True)
+    - show_home_icon: Show icon on home breadcrumb (default: True)
+    - separator: Separator character/icon (default: chevron icon)
+    - max_visible: Maximum items to show on mobile before collapsing (default: 3)
+    - container_class: Additional CSS classes for container
+
+Dependencies:
+    - Tailwind CSS for styling
+    - Font Awesome icons (for home icon and separator)
+    - breadcrumbs context processor for default breadcrumbs
+
+Accessibility:
+    - Uses <nav> element with aria-label="Breadcrumb"
+    - Ordered list for semantic structure
+    - aria-current="page" on current page item
+    - Hidden separators (aria-hidden) for screen readers

+    standard page navigation and HTMX-powered dynamic updates.
+
+Usage Examples:
+    Standard pagination:
+        {% include 'components/pagination.html' with page_obj=page_obj %}
+
+    HTMX-enabled pagination:
+        {% include 'components/pagination.html' with page_obj=page_obj use_htmx=True hx_target='#results' %}
+
+    Custom styling:
+        {% include 'components/pagination.html' with page_obj=page_obj size='sm' %}
+
+Parameters:
+    - page_obj: Django Page object from paginator (required)
+    - use_htmx: Enable HTMX for dynamic updates (optional, default: False)
+    - hx_target: HTMX target selector (optional, default: '#results')
+    - hx_swap: HTMX swap strategy (optional, default: 'innerHTML')
+    - hx_push_url: Whether to push URL to history (optional, default: 'true')
+    - size: Size variant 'sm', 'md', 'lg' (optional, default: 'md')

+    and optional link. Used for displaying metrics on detail pages.
+
+Usage Examples:
+    Basic stat:
+        {% include 'components/stats_card.html' with label='Total Rides' value=park.ride_count %}
+
+    Stat with icon:
+        {% include 'components/stats_card.html' with label='Rating' value='4.5/5' icon='fas fa-star' %}
+
+    Clickable stat:
+        {% include 'components/stats_card.html' with label='Total Rides' value=42 link=rides_url %}
+
+    Priority stat (highlighted):
+        {% include 'components/stats_card.html' with label='Operator' value=park.operator.name priority=True %}
+
+    Stat with subtitle:
+        {% include 'components/stats_card.html' with label='Height' value='250 ft' subtitle='76 meters' %}
+
+Parameters:
+    Required:
+    - label: Stat label/title
+    - value: Stat value to display

-Reusable status badge component with consistent styling.
+Status Badge Component
-Usage: {% include 'components/status_badge.html' with status="OPERATING" %}
+======================
-Usage (clickable): {% include 'components/status_badge.html' with status="OPERATING" clickable=True %}
+
+A unified, reusable status badge component for parks, rides, and other entities.
+
+Purpose:
+    Displays a status badge with consistent styling across the application.
+    Supports both static display and interactive HTMX-powered refresh.
+
+Usage Examples:
+    Basic badge (uses park_tags for config):
+        {% include 'components/status_badge.html' with status='OPERATING' %}
+
+    Clickable badge:
+        {% include 'components/status_badge.html' with status='OPERATING' clickable=True %}
+
+    Interactive badge with HTMX (for moderators):
+        {% include 'components/status_badge.html' with status=park.status badge_id='park-header-badge' refresh_url=park_badge_url refresh_trigger='park-status-changed' scroll_target='park-status-section' can_edit=perms.parks.change_park %}
+
+    Manual status display (without park_tags config lookup):
+        {% include 'components/status_badge.html' with status=obj.status status_display=obj.get_status_display manual_mode=True %}
+
+    Manual mode with custom classes:
+        {% include 'components/status_badge.html' with status=obj.status status_display=obj.get_status_display status_classes='bg-blue-100 text-blue-800' manual_mode=True %}
+
+Parameters:
+    Required:
+    - status: The status value (e.g., 'OPERATING', 'CLOSED_TEMP')
+
+    Optional (auto mode - uses park_tags):
+    - clickable: Enable click interactions (default: False)
+
+    Optional (HTMX mode):
+    - badge_id: ID for HTMX targeting
+    - refresh_url: URL for HTMX refresh on trigger
+    - refresh_trigger: HTMX trigger event name (e.g., 'park-status-changed')
+    - scroll_target: Element ID to scroll to on click
+    - can_edit: Whether user can edit/click the badge (default: False)
+
+    Optional (manual mode):
+    - manual_mode: Use status_display instead of park_tags config lookup (default: False)
+    - status_display: Human-readable status text (used when manual_mode=True)
+    - status_classes: CSS classes for badge styling (default: 'bg-gray-100 text-gray-800')
+
+    Optional (styling):
+    - size: Size variant 'sm', 'md', 'lg' (default: 'md')
+
+Status Classes (auto mode - defined in park_tags):
+    - OPERATING: Green (bg-green-100 text-green-800)
+    - CLOSED_TEMP: Yellow (bg-yellow-100 text-yellow-800)
+    - CLOSED_PERM: Red (bg-red-100 text-red-800)
+    - CONSTRUCTION: Orange (bg-orange-100 text-orange-800)
+    - DEMOLISHED: Gray (bg-gray-100 text-gray-800)
+    - RELOCATED: Purple (bg-purple-100 text-purple-800)
+    - SBNO: Amber (bg-amber-100 text-amber-800)
+
+Dependencies:
+    - park_tags template tags (for get_status_config filter, only needed in auto mode)
+    - HTMX (optional, for interactive features)
+    - Font Awesome icons (for dropdown indicator)
+
+Accessibility:
+    - Uses semantic button or span based on interactivity
+    - Provides appropriate focus states
+    - Uses color + text for status indication

+Usage Examples:
+  Alpine.js controlled modal:
+    {% include 'components/ui/dialog.html' with title='Confirm Action' content='Are you sure?' id='confirm-modal' %}
+    <button @click="$store.ui.openModal('confirm-modal')">Open Modal</button>
+
+  HTMX triggered modal (loads content dynamically):
+    <button hx-get="/modal/content" hx-target="#modal-container">Load Modal</button>
+    <div id="modal-container">
+      {% include 'components/ui/dialog.html' with title='Dynamic Content' %}
+    </div>
+
+  With footer actions:
+    {% include 'components/ui/dialog.html' with title='Delete Item' description='This cannot be undone.' footer='<button class="btn">Cancel</button><button class="btn btn-destructive">Delete</button>' %}
+
+Parameters:
+  - id: Modal ID (used for Alpine.js state management)
+  - title: Dialog title
+  - description: Dialog subtitle/description
+  - content: Main content (sanitized)
+  - footer: Footer content with actions (sanitized)
+  - open: Boolean to control initial open state (default: true for HTMX-loaded content)
+  - closable: Boolean to allow closing (default: true)
+  - size: 'sm', 'default', 'lg', 'xl', 'full' (default: 'default')
+  - class: Additional CSS classes for the dialog panel
+
+Accessibility:
+  - role="dialog" and aria-modal="true" for screen readers
+  - Focus trap within modal when open
+  - Escape key closes the modal
+  - Click outside closes the modal (backdrop click)
+
+Security: Content and footer are sanitized to prevent XSS attacks.

+Icon Component - SVG Icon Wrapper
+
+A component for rendering SVG icons consistently. Provides a library of common icons
+and supports custom SVG content. Replaces Font Awesome with inline SVGs for better
+customization and smaller bundle size.
+
+Usage Examples:
+  Named icon:
+    {% include 'components/ui/icon.html' with name='search' %}
+
+  With size:
+    {% include 'components/ui/icon.html' with name='menu' size='lg' %}
+
+  With custom class:
+    {% include 'components/ui/icon.html' with name='user' class='text-primary' %}
+
+  Custom SVG content:
+    {% include 'components/ui/icon.html' with svg='<path d="..."/>' %}
+
+Parameters:
+  - name: Icon name from the built-in library
+  - size: 'xs', 'sm', 'md', 'lg', 'xl' (default: 'md')
+  - class: Additional CSS classes
+  - svg: Custom SVG path content (for icons not in the library)
+  - stroke_width: SVG stroke width (default: 2)
+  - aria_label: Accessibility label (required for meaningful icons)
+  - aria_hidden: Set to 'false' for meaningful icons (default: 'true' for decorative)
+
+Available Icons:
+  Navigation: menu, close, chevron-down, chevron-up, chevron-left, chevron-right,
+              arrow-left, arrow-right, arrow-up, arrow-down, external-link
+  Actions: search, plus, minus, edit, trash, download, upload, copy, share, refresh
+  User: user, users, settings, logout, login
+  Status: check, x, info, warning, error, question
+  Media: image, video, music, file, folder
+  Communication: mail, phone, message, bell, send
+  Social: heart, star, bookmark, thumbs-up, thumbs-down
+  Misc: home, calendar, clock, map-pin, globe, sun, moon, eye, eye-off, lock, unlock

 Toast Notification Container Component
-Matches React frontend toast functionality with Sonner-like behavior
+======================================
+
+Enhanced toast notification system with Sonner-like behavior.
+
+Features:
+    - Multiple toast types (success, error, warning, info)
+    - Progress bar for auto-dismiss countdown
+    - Action button support (Undo, Retry, View)
+    - Toast stacking with max limit
+    - Persistent toast option (duration: 0)
+    - Accessible announcements
+
+Usage Examples:
+    Basic toast:
+        Alpine.store('toast').success('Item saved!')
+
+    With action:
+        Alpine.store('toast').success('Item deleted', 5000, {
+            action: { label: 'Undo', onClick: () => undoDelete() }
+        })
+
+    Persistent toast:
+        Alpine.store('toast').error('Connection lost', 0)
+
+    From HTMX via HX-Trigger header:
+        response['HX-Trigger'] = '{"showToast": {"type": "success", "message": "Saved!"}}'

+### Form Actions
+
+Submit and cancel buttons:
+
+```django
+{% include 'forms/partials/form_actions.html' %}
+
+{# With cancel #}
+{% include 'forms/partials/form_actions.html' with show_cancel=True cancel_url='/list/' %}

+
+## HTMX Integration
+
+### Inline Validation
+
+```django
+<form hx-post="/submit/" hx-target="#form-results">
+    {% for field in form %}
+        {% include 'forms/partials/form_field.html' with
+            field=field
+            hx_validate=True

+        %}
+    {% endfor %}
+    {% include 'forms/partials/form_actions.html' with show_loading=True %}
+</form>
+```
+
+### Validation Endpoint Response
+
+```django
+{# Success #}
+{% include 'forms/partials/field_success.html' with message='Valid!' %}
+
+{# Error #}
+{% include 'forms/partials/field_error.html' with errors=errors %}
+```
+
+## Custom Form Rendering
+
+For complete control, use the components directly:
+
+```django
+<form method="post" action="{% url 'submit' %}">
+    {% csrf_token %}
+
+    {# Non-field errors #}
+    {% if form.non_field_errors %}
+    <div class="mb-4 p-4 bg-red-50 rounded-lg" role="alert">
+        {% for error in form.non_field_errors %}
+            <p>{{ error }}</p>
+        {% endfor %}
+    </div>
+    {% endif %}
+
+    {# Custom field layout #}
+    <div class="grid grid-cols-2 gap-4">
+        {% include 'forms/partials/form_field.html' with field=form.first_name %}
+        {% include 'forms/partials/form_field.html' with field=form.last_name %}
+    </div>
+
+    {% include 'forms/partials/form_field.html' with field=form.email %}
+
+    {% include 'forms/partials/form_actions.html' with submit_text='Create Account' %}
+</form>
+```
+
+## CSS Classes
+
+The form components use these CSS classes (defined in `components.css`):
+
+- `.btn-primary` - Primary action button
+- `.btn-secondary` - Secondary action button
+- `.form-field` - Field wrapper
+- `.field-error` - Error message styling
+
+## Accessibility
+
+All form components include:
+
+- Labels properly associated with inputs (`for`/`id`)
+- Required field indicators with screen reader text
+- Error messages with `role="alert"`
+- Help text linked via `aria-describedby`
+- Invalid state with `aria-invalid`

+    success confirmations, error summaries, and loading states.
+
+Usage Examples:
+    Success state:
+        {% include 'forms/partials/form_submission_feedback.html' with state='success' message='Park saved successfully!' %}
+
+    Error state:
+        {% include 'forms/partials/form_submission_feedback.html' with state='error' message='Please fix the errors below' %}
+
+    Loading state:
+        {% include 'forms/partials/form_submission_feedback.html' with state='loading' message='Saving...' %}
+
+    With redirect countdown:
+        {% include 'forms/partials/form_submission_feedback.html' with state='success' message='Saved!' redirect_url='/parks/' redirect_seconds=3 %}
+
+Parameters:
+    Required:
+    - state: 'success', 'error', 'warning', 'loading' (default: 'success')
+    - message: Main feedback message
+
+    Optional:
+    - title: Optional title text
+    - show_icon: Show status icon (default: True)
+    - show_actions: Show action buttons (default: True)
+    - primary_action_text: Primary button text (default: varies by state)
+    - primary_action_url: Primary button URL
+    - secondary_action_text: Secondary button text
+    - secondary_action_url: Secondary button URL
+    - redirect_url: URL to redirect to after countdown
+    - redirect_seconds: Seconds before redirect (default: 3)
+    - errors: List of error messages (for error state)
+    - animate: Enable animations (default: True)
+
+Dependencies:
+    - Tailwind CSS for styling
+    - Alpine.js for countdown functionality
+    - Font Awesome icons
+
+Accessibility:
+    - Uses appropriate ARIA roles based on state
+    - Announces changes to screen readers

+# HTMX Templates and Patterns
+
+This directory contains HTMX-specific templates and components for ThrillWiki.
+
+## Overview
+
+HTMX is used throughout ThrillWiki for dynamic content updates without full page reloads. This guide documents the standardized patterns and conventions.
+
+## Directory Structure
+
+```
+htmx/
+├── components/           # Reusable HTMX components
+│   ├── confirm_dialog.html    # Confirmation modal
+│   ├── error_message.html     # Error display
+│   ├── filter_badge.html      # Filter tag/badge
+│   ├── inline_edit_field.html # Inline editing
+│   ├── loading_indicator.html # Loading spinners
+│   └── success_toast.html     # Success notification
+├── partials/             # HTMX response partials
+└── README.md             # This documentation
+```
+
+## Swap Strategies
+
+Use consistent swap strategies across the application:
+
+| Strategy | Use Case | Example |
+|----------|----------|---------|
+| `innerHTML` | Replace content inside container | List updates, search results |
+| `outerHTML` | Replace entire element | Status badges, table rows |
+| `beforeend` | Append items | Infinite scroll, new items |
+| `afterbegin` | Prepend items | New items at top of list |
+
+### Examples
+
+```html
+<!-- Replace content inside container -->
+<div id="results"
+     hx-get="/api/search"
+     hx-swap="innerHTML">
+
+<!-- Replace entire element (e.g., status badge) -->
+<span id="park-status"
+      hx-get="/api/park/status"
+      hx-swap="outerHTML">
+
+<!-- Infinite scroll - append items -->
+<div id="item-list"
+     hx-get="/api/items?page=2"
+     hx-trigger="revealed"
+     hx-swap="beforeend">
+```
+
+## Target Naming Conventions
+
+Follow these naming patterns for `hx-target`:
+
+| Pattern | Use Case | Example |
+|---------|----------|---------|
+| `#object-type-id` | Specific objects | `#park-123`, `#ride-456` |
+| `#section-name` | Page sections | `#results`, `#filters`, `#stats` |
+| `#modal-container` | Modal content | `#modal-container` |
+| `this` | Self-replacement | Status badges, inline edits |
+
+### Examples
+
+```html
+<!-- Target specific object -->
+<button hx-post="/api/parks/123/status"
+        hx-target="#park-123"
+        hx-swap="outerHTML">
+
+<!-- Target page section -->
+<form hx-post="/api/search"
+      hx-target="#results"
+      hx-swap="innerHTML">
+
+<!-- Self-replacement -->
+<span hx-get="/api/badge"
+      hx-target="this"
+      hx-swap="outerHTML">
+```
+
+## Custom Event Naming
+
+Use these conventions for custom HTMX events:
+
+| Pattern | Description | Example |
+|---------|-------------|---------|
+| `{model}-status-changed` | Status updates | `park-status-changed`, `ride-status-changed` |
+| `{model}-created` | New item created | `park-created`, `review-created` |
+| `{model}-updated` | Item updated | `ride-updated`, `photo-updated` |
+| `{model}-deleted` | Item deleted | `comment-deleted` |
+| `auth-changed` | Auth state change | User login/logout |
+
+### Triggering Events
+
+From Django views:
+```python
+response['HX-Trigger'] = 'park-status-changed'
+# or with data
+response['HX-Trigger'] = json.dumps({
+    'showToast': {'type': 'success', 'message': 'Status updated!'}
+})
+```
+
+Listening for events:
+```html
+<div hx-get="/api/park/header"
+     hx-trigger="park-status-changed from:body">
+```
+
+## Loading Indicators
+
+Use the standardized loading indicator component:
+
+```html
+<!-- Inline (in buttons) -->
+<button hx-post="/api/action" hx-indicator="#btn-loading">
+    Save
+    {% include 'htmx/components/loading_indicator.html' with id='btn-loading' inline=True size='sm' %}
+</button>
+
+<!-- Block (below content) -->
+<div hx-get="/api/data" hx-indicator="#loading">
+    Content
+</div>
+{% include 'htmx/components/loading_indicator.html' with id='loading' message='Loading...' %}
+
+<!-- Overlay (covers container) -->
+<div class="relative" hx-get="/api/data" hx-indicator="#overlay">
+    Content
+    {% include 'htmx/components/loading_indicator.html' with id='overlay' mode='overlay' %}
+</div>
+```
+
+## Error Handling
+
+HTMX errors are handled globally in `base.html`. The system:
+
+1. Shows toast notifications for different HTTP status codes
+2. Handles timeouts (30 second default)
+3. Handles network errors
+4. Supports retry logic
+
+### Custom Error Responses
+
+Return error templates for 4xx/5xx responses:
+```html
+{% include 'htmx/components/error_message.html' with title='Error' message='Something went wrong.' %}
+```
+
+## Toast Notifications via HTMX
+
+Trigger toast notifications from server responses:
+
+```python
+from django.http import JsonResponse
+
+def my_view(request):
+    response = render(request, 'partial.html')
+    response['HX-Trigger'] = json.dumps({
+        'showToast': {
+            'type': 'success',  # success, error, warning, info
+            'message': 'Action completed!',
+            'duration': 5000  # optional, in milliseconds
+        }
+    })
+    return response
+```
+
+## Form Validation
+
+Use inline HTMX validation for forms:
+
+```html
+<input type="text"
+       name="username"
+       hx-post="/api/validate/username"
+       hx-trigger="blur changed delay:500ms"
+       hx-target="#username-feedback"
+       hx-swap="innerHTML">
+<div id="username-feedback"></div>
+```
+
+Validation endpoint returns:
+```html
+<!-- Success -->
+{% include 'forms/partials/field_success.html' with message='Username available' %}
+
+<!-- Error -->
+{% include 'forms/partials/field_error.html' with errors=errors %}
+```
+
+## Common Patterns
+
+### Search with Debounce
+
+```html
+<input type="search"
+       hx-get="/api/search"
+       hx-trigger="keyup changed delay:300ms"
+       hx-target="#results"
+       hx-indicator="#search-loading">
+```
+
+### Modal Content Loading
+
+```html
+<button hx-get="/api/park/123/edit"
+        hx-target="#modal-container"
+        hx-swap="innerHTML"
+        @click="$store.modal.open()">
+    Edit
+</button>
+```
+
+### Infinite Scroll
+
+```html
+<div id="items">
+    {% for item in items %}
+        {% include 'item.html' %}
+    {% endfor %}
+
+    {% if page_obj.has_next %}
+    <div hx-get="?page={{ page_obj.next_page_number }}"
+         hx-trigger="revealed"
+         hx-swap="outerHTML"
+         hx-select="#items > *">
+        {% include 'htmx/components/loading_indicator.html' %}
+    </div>
+    {% endif %}
+</div>
+```
+
+### Status Badge Refresh
+
+```html
+<span id="park-header-badge"
+      hx-get="{% url 'parks:park_header_badge' park.slug %}"
+      hx-trigger="park-status-changed from:body"
+      hx-swap="outerHTML">
+    {% include 'components/status_badge.html' with status=park.status %}
+</span>
+```
+
+## Best Practices
+
+1. **Always specify `hx-swap`** even for default behavior (clarity)
+2. **Use meaningful target IDs** following naming conventions
+3. **Include loading indicators** for all async operations
+4. **Handle errors gracefully** with user-friendly messages
+5. **Debounce search/filter inputs** to reduce server load
+6. **Use `hx-push-url`** for URL changes that should be bookmarkable
+7. **Provide fallback** for JavaScript-disabled browsers where possible
+
+## Security Considerations
+
+- CSRF tokens are automatically included via `hx-headers` in base.html
+- All HTMX endpoints should validate permissions
+- Use Django's `@require_http_methods` decorator
+- Sanitize any user input before rendering
+
+## Debugging
+
+Enable HTMX debugging in development:
+```javascript
+htmx.logAll();
+```
+
+Check browser DevTools Network tab for HTMX requests (look for `HX-Request: true` header).

+# HTMX Components
+
+This directory contains HTMX-related template components for loading states, error handling, and success feedback.
+
+## Loading State Guidelines
+
+### When to Use Each Type
+
+| Scenario | Component | Example |
+|----------|-----------|---------|
+| Initial page load, full content replacement | Skeleton screens | Parks list loading |
+| Button actions, form submissions | Loading indicator (inline) | Submit button spinner |
+| Partial content updates | Loading indicator (block) | Search results loading |
+| Container replacement | Loading indicator (overlay) | Modal content loading |
+
+### Components
+
+#### loading_indicator.html
+
+Standardized loading indicator for HTMX requests with three modes:
+
+**Inline Mode** - For buttons and links:
+```django
+<button hx-post="/api/action" hx-indicator="#btn-loading">
+    Save
+    {% include 'htmx/components/loading_indicator.html' with id='btn-loading' mode='inline' %}
+</button>
+```
+
+**Block Mode** (default) - For content areas:
+```django
+<div hx-get="/api/list" hx-indicator="#list-loading">
+    <!-- Content -->
+</div>
+{% include 'htmx/components/loading_indicator.html' with id='list-loading' %}
+```
+
+**Overlay Mode** - For containers:
+```django
+<div class="relative" hx-get="/api/data" hx-indicator="#overlay-loading">
+    <!-- Content to cover -->
+    {% include 'htmx/components/loading_indicator.html' with id='overlay-loading' mode='overlay' %}
+</div>
+```
+
+#### Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `id` | str | - | ID for hx-indicator targeting |
+| `message` | str | "Loading..." | Loading text to display |
+| `mode` | str | "block" | 'inline', 'block', or 'overlay' |
+| `size` | str | "md" | 'sm', 'md', or 'lg' |
+| `spinner` | str | "border" | 'spin' (fa-spinner) or 'border' (CSS) |
+
+## Skeleton Screens
+
+Located in `components/skeletons/`, these provide content-aware loading placeholders:
+
+### Available Skeletons
+
+| Component | Use Case |
+|-----------|----------|
+| `list_skeleton.html` | List views, search results |
+| `card_grid_skeleton.html` | Card-based grid layouts |
+| `detail_skeleton.html` | Detail/show pages |
+| `form_skeleton.html` | Form loading states |
+| `table_skeleton.html` | Data tables |
+
+### Usage with HTMX
+
+```django
+{# Initial content shows skeleton, replaced by HTMX #}
+<div id="parks-list"
+     hx-get="/parks/"
+     hx-trigger="load"
+     hx-swap="innerHTML">
+    {% include 'components/skeletons/card_grid_skeleton.html' with cards=6 %}
+</div>
+```
+
+### With hx-indicator
+
+```django
+<div id="results">
+    <!-- Results here -->
+</div>
+
+{# Skeleton shown during loading #}
+<div id="results-skeleton" class="htmx-indicator">
+    {% include 'components/skeletons/list_skeleton.html' %}
+</div>
+```
+
+## Error Handling
+
+### error_message.html
+
+Displays error messages with consistent styling:
+
+```django
+{% include 'htmx/components/error_message.html' with
+    message="Unable to load data"
+    show_retry=True
+    retry_url="/api/data"
+%}
+```
+
+### Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `message` | str | - | Error message text |
+| `code` | str | - | HTTP status code |
+| `show_retry` | bool | False | Show retry button |
+| `retry_url` | str | - | URL for retry action |
+| `show_report` | bool | False | Show "Report Issue" link |
+
+## Success Feedback
+
+### success_toast.html
+
+Triggers a toast notification via HTMX response:
+
+```django
+{% include 'htmx/components/success_toast.html' with
+    message="Park saved successfully"
+    type="success"
+%}
+```
+
+### Using HX-Trigger Header
+
+From views, trigger toasts via response headers:
+
+```python
+from django.http import HttpResponse
+
+def save_park(request):
+    # ... save logic ...
+    response = HttpResponse()
+    response['HX-Trigger'] = json.dumps({
+        'showToast': {
+            'type': 'success',
+            'message': 'Park saved successfully'
+        }
+    })
+    return response
+```
+
+## HTMX Configuration
+
+The base template configures HTMX with:
+
+- 30-second timeout
+- Global view transitions enabled
+- Template fragments enabled
+- Comprehensive error handling
+
+### Swap Strategies
+
+| Strategy | Use Case |
+|----------|----------|
+| `innerHTML` | Replace content inside container (lists, search results) |
+| `outerHTML` | Replace entire element (status badges, individual items) |
+| `beforeend` | Append items (infinite scroll) |
+| `afterbegin` | Prepend items (new items at top) |
+
+### Target Naming Conventions
+
+- `#object-type-id` - For specific objects (e.g., `#park-123`)
+- `#section-name` - For page sections (e.g., `#results`, `#filters`)
+- `#modal-container` - For modals
+- `this` - For self-replacement
+
+### Custom Events
+
+- `{model}-status-changed` - Status updates (e.g., `park-status-changed`)
+- `auth-changed` - Authentication state changes
+- `{model}-created` - New item created
+- `{model}-updated` - Item updated
+- `{model}-deleted` - Item deleted
+
+## Best Practices
+
+1. **Always specify hx-indicator** for user feedback
+2. **Use skeleton screens** for initial page loads and full content replacement
+3. **Use inline indicators** for button actions
+4. **Use overlay indicators** for modal content loading
+5. **Add aria attributes** for accessibility (role="status", aria-busy)
+6. **Clean up loading states** after request completion (automatic with HTMX)

-Loading Indicator Component
+HTMX Loading Indicator Component
+================================
 
-Displays a loading spinner for HTMX requests.
+A standardized loading indicator for HTMX requests.
 
-Optional context:
+Purpose:
-  - size: 'sm', 'md', or 'lg' (defaults to 'md')
+    Provides consistent loading feedback during HTMX requests.
-  - inline: Whether to render inline (defaults to false)
+    Can be used inline, block, or as an overlay.
-  - message: Loading message text (defaults to 'Loading...')
+
-  - id: Optional ID for the indicator element
+Usage Examples:
+    Inline spinner (in button/link):
+        <button hx-get="/api/data" hx-indicator="#btn-loading">
+            Load Data
+            {% include 'htmx/components/loading_indicator.html' with id='btn-loading' inline=True size='sm' %}
+        </button>
+
+    Block indicator (below content):
+        <div hx-get="/api/list" hx-indicator="#list-loading">
+            Content here
+        </div>
+        {% include 'htmx/components/loading_indicator.html' with id='list-loading' message='Loading items...' %}
+
+    Overlay indicator (covers container):
+        <div class="relative" hx-get="/api/data" hx-indicator="#overlay-loading">
+            Content to cover
+            {% include 'htmx/components/loading_indicator.html' with id='overlay-loading' mode='overlay' %}
+        </div>
+
+    Custom spinner:
+        {% include 'htmx/components/loading_indicator.html' with id='custom-loading' spinner='border' %}
+
+Parameters:
+    Optional:
+    - id: Unique identifier for the indicator (used with hx-indicator)
+    - message: Loading text to display (default: 'Loading...')
+    - mode: 'inline', 'block', or 'overlay' (default: 'block')
+    - inline: Shortcut for mode='inline' (backwards compatible)
+    - size: 'sm', 'md', 'lg' (default: 'md')
+    - spinner: 'spin' (fa-spinner) or 'border' (CSS animation) (default: 'border')
+
+Dependencies:
+    - HTMX for .htmx-indicator class behavior
+    - Tailwind CSS for styling
+    - Font Awesome icons (for 'spin' spinner)
+
+Accessibility:
+    - Uses role="status" and aria-live="polite" for screen readers
+    - aria-hidden while not loading (HTMX handles visibility)
+    - Loading message announced to screen readers
