   Repricer — application stylesheet
   Built on the Keystrom / Materio design system (ds/tokens.css).
   Brand decision: DESIGN.md §14 flags an unresolved primary discrepancy
   (violet #8C57FF in tokens.css vs blue #3A6FF7 in index.html). Resolved to
   the blue family here and centralised in ONE block so the whole app
   re-themes from two values.
