/* ============================================
   HOMEPAGE FEATURE 6 — Merchandise Store
   Modular CSS for the dynamically-injected merchandise section.
   Mobile-first responsive grid with full-screen store modal,
   product detail modal, cart drawer, order form, and success state.

   ARCHITECTURE:
   - Uses design tokens (CSS custom properties) from homepage.css
   - Mobile-first with breakpoints at 640px, 768px, 1024px, 1440px
   - Store modal: z-index 190 (full-screen browse overlay)
   - Modals use z-index 200 (detail, cart, order) and 300 (success)
   - Skeleton loaders for perceived performance
   - prefers-reduced-motion respected throughout
   - Touch-device optimizations for mobile
   - AWS Console Dark Mode color system

   SECTIONS:
   1. Section Container & Grid
   2. Product Cards
   3. Quantity Controls
   4. Browse Actions
   5. Cart Summary Bar (sticky)
   6. Store Modal — Full-Screen Browse Overlay
   7. Product Detail Modal
   8. Cart Modal & Table
   9. Order Form Modal
   10. Success Overlay
   11. Empty State & Skeleton
   12. Responsive Overrides
   13. Touch Device Overrides
   14. Reduced Motion
