- Modern card-based layout with vertical icon rail, breadcrumb nav, inline search
- Admin mode: edit/create/delete pages and offers, drag & drop reorder via HK API
- Favorites system: heart on furni, star on pages, localStorage persistence
- Redesigned product card with price pills, dynamic quantity spinner
- Upgraded trophies (filter tabs, parchment textarea), pets (breed/color flow),
  custom prefix (dynamic color boxes)
- Font fix: Ubuntu Regular, proper @font-face declarations
- New Tailwind design tokens and CatalogTexts.json for localization
