   QSC — PHARMA GRADE DESIGN SYSTEM
   Clean clinical light theme: white canvas, cool light-blue-gray tints,
   one decisive pharma blue, clinical mint for verified/COA/success,
   red reserved for warnings & sale urgency.
   Type: Funnel Display (display) + Funnel Sans (body) + Red Hat Mono (data).
   NOTE: legacy variable names are kept but remapped to the light pharma
   palette so every page stylesheet inherits the theme.
