/* =============================================================================
   Responsive — Tablet & Mobile Layout
   Mobile-first enhancements layered on top of the base CSS.

   Strategy (Facebook / YouTube mobile pattern):
   ─ ≤ 768px  (mobile): sidebar hidden, bottom nav bar, full-width content,
                         hamburger opens a full overlay drawer
   ─ 769–1024px (tablet): sidebar stays as 64px icon rail,
                           content takes remaining width
   ─ ≥ 1025px (desktop): unchanged from base CSS
