/**
 * App Layout System
 *
 * This file controls the overall layout structure for the app pages.
 * It uses a flexbox layout to ensure:
 * 1. Fixed header menu at top (never overlaps content)
 * 2. Content area grows to fill available space (scrollable)
 * 3. Footer stays at bottom of content (doesn't ride up with large gaps)
 *
 * Layout Structure:
 * - body: 100vh height, flexbox column
 *   ├── #app-menu-desktop/mobile: Fixed header (flex-shrink: 0)
 *   └── #app-container: Main content area (flex-grow: 1, scrollable)
 *       ├── .app-title: Page title (flex-shrink: 0)
 *       ├── .app-content: Content wrapper (flex-grow: 1)
 *       │   └── .app-content-inner: Actual content
 *       └── .app-bottom-menu: Action buttons (flex-shrink: 0)
