/* Mobile / PWA layer.
 *
 * The desktop CSS lives in styles.css; this file only adds responsive
 * behaviour for screens ≤ 900px (tablets and phones). The pattern:
 *   - Hide the sidebar by default on mobile, slide it in via .sidebar-open
 *   - Show the hamburger button (hidden on desktop)
 *   - Stack two-column grids vertically
 *   - Make tables horizontally scrollable instead of squishing
 *   - Larger tap targets, denser typography
