   Rock Celine — v2 design system
   ---------------------------------------------------------------------
   Built on the original's confirmed DNA (amber accent #f9ad4a, dark
   curtain hero, Roboto + Raleway, minimalist high-contrast) and pushed
   with real design craft: transparent→solid header, organic wave
   dividers, deliberate typographic rhythm, refined cards.

   Sections:
     1. Tokens          6. Header / nav
     2. Reset / base    7. Hero
     3. Type            8. Cards & grids
     4. Layout          9. CTA band
     5. Buttons        10. Footer & misc
