+- Consolidated toggle button styles (shared between mega and standard menu items)
+- First-level navigation styling with animated underlines

+- **Navigation Link**: Base link styling only
+- **Mega Menu Item**: Dropdown container and content styling
+- **Standard Menu Item**: Basic positioning and submenu wrapper styling

+## Styling Architecture
+
+### Centralized Coordinator Pattern
+
+The navigation system uses a **centralized coordinator pattern** where the Navigation Wrapper acts as the central styling authority:
+
+```
+Navigation Wrapper (Coordinator)
+├── Toggle Button Styles (shared by mega & standard menu items)
+├── First-Level Navigation Styling (animated underlines, hover states)
+├── Context-Specific Overrides (Primary vs Utility menu)
+└── Responsive Adaptations (mobile behavior)
+
+Individual Blocks (Content-Specific)
+├── Navigation Link: Base link styles only
+├── Mega Menu Item: Dropdown container & content
+└── Standard Menu Item: Basic positioning & submenu wrapper
+```
+
+### Key Benefits
+
+**Eliminates Code Duplication**: Shared styles are defined once in Navigation Wrapper
+**Single Source of Truth**: Navigation behavior modifications happen in one place
+**Clear Separation**: Each block has a specific, well-defined styling responsibility
+**Easy Maintenance**: Changes to navigation styling require updates to only one file
+**Consistent Experience**: Unified first-level navigation behavior across all menu types
+
+### CSS File Organization
+
+**Navigation Wrapper** (`navigation-wrapper/style.pcss`):
+- Toggle button styles (consolidated)
+- Primary navigation first-level styles
+- Utility menu style overrides
+- Responsive behavior
+
+**Individual Block Files**:
+- **Navigation Link**: Base link foundation only
+- **Mega Menu Item**: Dropdown content and container queries
+- **Standard Menu Item**: Simple positioning and submenu wrapper

+## Development Guidelines
+
+### Working with the Centralized Architecture
+
+#### **Making Navigation Styling Changes**
+
+**For First-Level Navigation Changes**: Edit `navigation-wrapper/style.pcss`
+- Toggle button styling (padding, colors, hover states)
+- Animated underlines and transitions
+- Font sizes and spacing
+- Context-specific behavior (Primary vs Utility)
+
+**For Individual Block Content**: Edit respective block files
+- `navigation-link/style.pcss`: Base link foundation only
+- `mega-menu-item/style.pcss`: Dropdown content and container queries
+- `standard-menu-item/style.pcss`: Basic positioning and submenu wrapper
+
+### Customization Points
+
+- **Navigation Wrapper**: Central coordinator for all first-level styling
+- **Patterns**: Modify `patterns/mega-dropdown` for mega menu layouts
+- **Individual Blocks**: Content-specific styling only
+- **Context Selectors**: Use `.site-header__navigation` and `.site-header__utility-menu` for targeting
