/* ============================================
   Modern Blinds — Primitive Design Tokens (Tier 1)
   ============================================
   Raw scales. No semantics — just values.
   Naming: DTCG-aligned [category]-[property]-[variant].
   Loaded FIRST via base.html + base_lp.html.
   Downstream: tokens-semantic.css references these.

   Also declares the @layer order for the whole app and holds
   the global reset + .container utility in @layer base.
