/* =========================================
   Typography Scaling

   The heading tokens in variables.css are already fluid clamp() values taken
   from the concept, so they need no per-breakpoint overrides — adding fixed
   sizes here would override the clamp and break the intended scale.
   Only the reading measure is adjusted below.
   ========================================= */
