/* ============================================================
   stray-commerce — PRIMITIVE TOKENS  (FINAL)
   Raw, context-free values: the foundation of the design system.
   This file is the swappable SKIN. Re-skin by changing values
   here (and in semantic.css) — never edit components.

   BREAKPOINTS (reference — CSS can't tokenize media conditions):
     tablet  : 768px  (48rem)
     desktop : 1024px (64rem)
   Use these exact values in every @media rule across the theme.
