/* ============================================================================
   Worthly site - design system
   ----------------------------------------------------------------------------
   Reusable by every page in /site. Do not fork per page; add a class here.

   CONTENTS
     1. Tokens (same palette as frontend/src/index.css, plus site-only extras)
     2. Base & atmosphere (mesh light, grain)
     3. Layout primitives   .container .section .split .grid .stack
     4. Type                .eyebrow .h-mega .h-hero .h-display .h-xl .lede .body
     5. Surfaces            .glass .card (gradient hairline + pointer light)
     6. Buttons & small UI  .btn .tag .caption .link-arrow
     7. Header, menu, footer
     8. Motion primitives   .reveal  [data-count]  [data-scrub]  .pin
     9. Components          .hero .stage .marquee .quotes .wall .ledger .doors
                            .device .chart .donut .bars .dl .log .community .faq
                            .page-hero .prose
    10. Responsive & reduced motion

   MOTION CONTRACT: every hidden/animated start state is gated by `html.motion`
   (set in <head> only when the user has NOT asked for reduced motion). Without
   it - no JS, or reduced motion - the page is complete and static.
