/* PUPPROPER — Mobile UX pass (v4 patch)
 * ─────────────────────────────────────────────────────────────────
 * Fixes the 3 mobile blockers identified in brand/10-design-direction-v4.md:
 *   1. Hamburger drawer (replaces hidden-nav at ≤768px)
 *   2. Bottom tab bar (mobile only, ≤720px)
 *   3. Sticky add-to-bag on PDPs (mobile only)
 *   4. 44px touch target enforcement
 * Loads after main.css; overrides without re-architecting.
 * ─────────────────────────────────────────────────────────────────
