/* ═══════════════════════════════════════════════════════════════════════
   BBA Peptides — design system (SPEC §3, redesign 2026-10). ONE source.
   docs/redesign-2026-10/DESIGN-SYSTEM.md documents every token and component.

   Three cascade layers + one unlayered shell:
     @layer bba-ds.tokens      — :root tokens + legacy aliases (every page). A page's
                                 own unlayered :root wins, so a not-yet-converted page
                                 keeps its look; a page that lacks a name gets the alias.
     @layer bba-ds.base        — reset + type, only under <html class="bba-ds">.
     @layer bba-ds.components  — .btn .chip .field .card-vial .shelf .badge-coa .price
                                 .drawer .sheet .toast …, only under html.bba-ds.
     shell (unlayered)         — .site-header / .site-footer / .site-drawer / .bba-skip,
                                 rendered by site-header.js + site-footer.js on EVERY
                                 page, so they are written to survive hostile host rules.
   A page opts into base + components with <html class="bba-ds">. Nothing here defines
   a color, size or radius outside :root (scripts/check_ds_tokens.mjs enforces it).
