/* ============================================================
   945 CLUB — SHARED DESIGN TOKENS
   Single source of truth for both the storefront and the admin panel.
   Extracted verbatim from css/main.css so the two surfaces cannot drift.

   The admin panel redefines the *colour* tokens for dark in css/admin.css and
   keeps --admin-* as thin aliases over them, so its 175 existing var(--admin-*)
   references (98 of which live in admin.html inline styles and js/admin.js
   template strings) keep working untouched.

   Theme-invariant tokens -- fonts, radii, spacing, easing -- are NOT overridden;
   sharing them is what makes the two surfaces read as one product.
