/* =============================================================
   VALHALLA PEPTIDES — Mobile Nav Additive Overrides (Phase Mobile Nav)
   Date: 2026-05-25
   Scope: Additive overrides for the existing CC#2 Block C drawer.

   Additive only — keeps existing structure & classnames:
   - Hamburger 32×32 → 44×44 (WCAG 2.5.5)
   - Breakpoint ≤768 → ≤1024 (tablets now also get drawer UX)
   - Adds drawer-head (logo + close button) and drawer-foot styling
   - Body scroll lock decoupled from media query

   Loaded by inc/mobile-nav.php @ priority 1001 — cascades AFTER
   header.css (inline in vp-header.php) and mobile-optimizations.css.
   Color tokens (#D4AF37) match existing theme; do NOT switch to
   #C9A055 (separate Phase 5 design-system audit task).
   ============================================================= */

/* ============================================================
   Body scroll lock — runs at any breakpoint where drawer is open.
   Existing CSS scoped this to ≤768; lift to global so ≤1024 also
   locks scroll once hamburger drawer engages.
