   ETKLOCK — Design System
   Colour is scoped to zones: components read semantic tokens
   (--surface, --text, --line, --btn-*) and a wrapper with
   .zone-light / .zone-dark redefines them. One card rule works
   on cream and on near-black; .on-dark pins a card dark
   wherever it sits.

   1. Brand constants & scales
   2. Zone palettes
   3. Base & utilities
   4. Buttons, links, pills
   5. Top bar, header & navigation
   6. Hero, marquee, sliding type
   7. Home sections
   8. Products
   9. Support
   10. About
   11. Contact & forms
   12. Footer, 404, floating CTA
   13. Motion & parallax
