/* ==========================================================================
   ClipZap landing — single stylesheet.

   Structure:
     1. Reset / base
     2. Design tokens (light + dark via data-theme)
     3. Typography
     4. Layout primitives (container, grids)
     5. Components: header, hero, buttons, cards, kbd, footer
     6. Sections (features, categories, shortcuts, audience, privacy, download)
     7. Animations + reveal states
     8. Responsive (mobile-first → ≥640 → ≥960 → ≥1200)

   Conventions:
     - Mobile-first; min-width media queries only.
     - All colors via tokens; never inline hex except for the category
       dots, which intentionally use brand-fixed values from `categories.ts`.
     - 4 px spacing scale (0.25 rem multiples).
