/* Sales Guide — Caparol Georgia
   Brand identity: white chrome + real brand logos; accent follows the brand
   (Caparol red / Alpina blue); the Caparol elephant stripe is the signature
   motif (login card, header rule). All selectors used by app.js preserved.
   2026-07-19 design pass: FiraGO type, token scale, welcome cards, guided
   panel, product/margin cards — critic-panel corrections applied. */
