 * Lok-N-Blok shared UI layer
 * Loaded by every page. Targets the shared scaffolding (.sidebar, .main,
 * .card, .btn, etc.) without overriding page-specific layout.
 *
 * Goals:
 *   - Real mobile responsiveness with a hamburger drawer on every sidebar page
 *   - 16px form fields (no iOS zoom on focus)
 *   - Touch-friendly tap targets (≥40px)
 *   - Safe-area insets for notched phones
 *   - Smooth scrollbars + scroll-shadow polish
 *   - Accessible focus-visible rings
 *   - prefers-reduced-motion respect
 *   - Print stylesheet that hides nav and prints clean cards
