# ThrillWiki Design System - Component Library

## Overview
Comprehensive component library for ThrillWiki's frontend redesign, providing reusable UI patterns that implement the design token system consistently across all templates.

## Component Categories

### 1. Layout Components

#### Container
```html
<!-- Base container with responsive padding -->
<div class="container">
  <!-- Content -->
</div>

<!-- Fluid container (full width) -->
<div class="container-fluid">
  <!-- Content -->
</div>

<!-- Constrained container (max-width) -->
<div class="container-constrained">
  <!-- Content -->
</div>
```

```css
.container {
  width: 100%;
  margin-left: auto;
  margin-right: auto;
  padding-left: var(--spacing-container-sm);
  padding-right: var(--spacing-container-sm);
}

@media (min-width: 640px) {
  .container {
    padding-left: var(--spacing-container-md);
    padding-right: var(--spacing-container-md);
  }
}

@media (min-width: 1024px) {
  .container {
    padding-left: var(--spacing-container-lg);
    padding-right: var(--spacing-container-lg);
  }
}

.container-constrained {
  max-width: 1280px;
}

.container-fluid {
  width: 100%;
  padding-left: var(--spacing-container-xs);
  padding-right: var(--spacing-container-xs);
}
```

#### Grid System
```html
<!-- Responsive grid -->
<div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
  <div class="grid-item">Item 1</div>
  <div class="grid-item">Item 2</div>
  <div class="grid-item">Item 3</div>
</div>

<!-- Auto-fit grid -->
<div class="grid-auto-fit">
  <div class="grid-item">Item 1</div>
  <div class="grid-item">Item 2</div>
  <div class="grid-item">Item 3</div>
</div>
```

```css
.grid-auto-fit {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(280px, 1fr));
  gap: var(--spacing-layout-md);
}

.grid-item {
  min-width: 0; /* Prevent grid blowout */
}
```

## Alpine.js Component Patterns

### Theme Toggle Component
```javascript
Alpine.data('themeToggle', () => ({
  isDark: localStorage.getItem('theme') === 'dark' || 
         (!localStorage.getItem('theme') && window.matchMedia('(prefers-color-scheme: dark)').matches),
  
  init() {
    this.updateTheme();
  },
  
  toggle() {
    this.isDark = !this.isDark;
    this.updateTheme();
  },
  
  updateTheme() {
    if (this.isDark) {
      document.documentElement.classList.add('dark');
      localStorage.setItem('theme', 'dark');
    } else {
      document.documentElement.classList.remove('dark');
      localStorage.setItem('theme', 'light');
    }
  }
}));
```

### Modal Component
```javascript
Alpine.data
