            <!-- Dynamic content loaded here -->
        </div>
    </main>
</div>
```

**File References:**
- Base layout: `/Views/Shared/_Layout.cshtml`
- Navigation logic: `/wwwroot/js/shared.js` (lines 1810-1848)

## Visual & Responsive Design

### Design System Foundation
Built on **Bootstrap 5** with extensive customizations for mobile-first responsive design and comprehensive dark mode support.

### Mobile-First Architecture
```css
html {
    font-size: 14px; /* Base mobile size */
}

@media (min-width: 768px) {
    html {
        font-size: 16px; /* Desktop scaling */
    }
}
```

### Dark Mode Implementation
Sophisticated theme system using Bootstrap 5's `data-bs-theme` attribute:

```html
<html lang="en" data-bs-theme="@(useDarkMode ? "dark" : "light")">
```

**Theme-aware components** with backdrop blur effects:
```css
html[data-bs-theme="dark"] .table-context-menu {
    background-color: rgba(33, 37, 41, 0.7);
    backdrop-filter: blur(10px);
}
```

### Mobile Modal Excellence
Full-screen mobile modals with hardware-accelerated animations:
```css
@media (max-width: 768px) {
    .modal-dialog {
        margin: 0;
        width: 100vw;
        height: 100vh;
        max-width: none;
        max-height: none;
    }
    
    .modal.fade .modal-dialog {
        transform: translateY(100%);
        transition: transform 0.3s cubic-bezier(0.25, 0.46, 0.45, 0.94);
    }
}
```

### Progressive Web App (PWA) Features
