   that no longer exist in menu-build.js (which now generates .nav-item, .nav-group-title,

   margin-left: 64px !important` rules were dead code that also broke the mobile slide-in
   sidebar (clipping all menu text). That block has been removed.
   Mobile sidebar behavior is now defined entirely in the `@media (max-width: 992px)`
   block near the top of the RESPONSIVE section, plus the R15_MOBILE block at the end
   of this file (backdrop, touch targets, safe-area, brand-name hide). */

/* ============================================================
   ============== R15_MOBILE: Mobile Sidebar Polish ===========
   ============================================================
   Companion to the `@media (max-width: 992px)` block in the
   RESPONSIVE section. Adds:
   - Backdrop overlay shown when sidebar is open on mobile
     (tap outside to close). Backdrop sits below the sidebar
     (z-index 1019 vs sidebar 1020) but above page content.
   - Touch-friendly tap targets for .nav-item / .nav-group-title
     (≥40px height) — only on mobile, doesn't touch desktop.
   - iOS notch / safe-area-inset support so the hamburger button
     in the header isn't hidden under the notch.
   - Compact header on very small screens (≤480px): hide brand
     name text, keep hamburger + logo + avatar only.
   Desktop (>992px) is completely unaffected. */
