+
+## Component Architecture
+
+### 1. LocationMapComponent ✅
+Main interactive map component handling:
+- Map initialization and rendering using Leaflet.js
+- Marker management with layer groups
+- Viewport control with zoom/pan
+- Event handling for user interactions
+- Custom controls for zoom and centering
+- Selected location display
+- Mobile-responsive layout
+
+Technical Features:
+```php
+class LocationMapComponent extends Component
+{
+    public ?float $latitude;
+    public ?float $longitude;
+    public int $zoom = 13;
+    public array $markers = [];
+    public ?array $selectedLocation;
+    public bool $interactive = true;
+    public bool $showControls = true;
+}
+```
+
+Event System:
+- locationSelected: When a location is chosen
+- markerClicked: When a map marker is clicked
+- mapMoved: When the viewport changes
+- zoomChanged: When zoom level updates
+
+### 2. LocationSelectorComponent ✅
+Location selection interface providing:
+- Address search with autocomplete
+- Map-based coordinate selection
+- Current location detection
+- Validation feedback
+- Selection confirmation
+
+Technical Features:
+```php
+class LocationSelectorComponent extends Component
+{
+    // Search State
+    public string $searchQuery = '';
+    public array $searchResults = [];
+    public bool $isSearching = false;
+    public ?string $validationError = null;
+
+    // Location State
+    public ?float $latitude = null;
+    public ?float $longitude = null;
+    public ?string $formattedAddress = null;
+    public bool $isValidLocation = false;
+
+    // UI State
+    public bool $showSearchResults = false;
+    public bool $isLoadingLocation = false;
+    public string $mode = 'search'; // search|coordinates|current
+}
+```
+
+Event System:
+- locationSelected: When a location is confirmed
+- searchUpdated: When search query changes
+- coordinatesChanged: When coordinates are updated
+- validationFailed: When validation fails
+- modeChanged: When selection mode changes
+- requestCurrentLocation: When requesting browser geolocation
+
+### 3. LocationDisplayComponent ✅
+Multiple location display component with:
+- Read-only map view
+- Marker clustering
+- Info window popups
+- Custom marker icons
+- Zoom to fit markers
+
+Technical Features:
+```php
+class LocationDisplayComponent extends Component
+{
+    // Map Configuration
+    public array $markers = [];
+    public bool $showClusters = true;
+    public int $clusterRadius = 50;
+    public int $defaultZoom = 13;
+    public ?array $bounds = null;
+
+    // Display Settings
+    public bool $showInfoWindow = false;
+    public ?array $activeMarker = null;
+    public array $customMarkers = [];
+    public array $markerCategories = [];
+
+    // State Management
+    public bool $isLoading = true;
+    public ?string $error = null;
+    public array $visibleMarkers = [];
+}
+```
+
+Event System:
+- markerClicked: When a marker is selected
+- clusterClicked: When a cluster is selected
+- boundsChanged: When map viewport changes
+- markersUpdated: When markers are refreshed
+- infoWindowClosed: When info window is closed
+
+## Technical Implementation
+
+### Map Provider Integration ✅
+- OpenStreetMap for base map tiles
+- Leaflet.js for map interface and controls
+- Dynamic script/style loading
+- Efficient tile caching
+- Custom control implementation
+
+### Performance Optimizations ✅
