/* store.css — BQT-Store. Light theme on the BQT-Mobile-UI tokens
   (BQT-Products/BQT-Mobile-UI/tokens/tokens.css), the same look as the platform web console and apps:
   light ground, white surfaces, navy ink and headings, gold #f1b621 as a fill with navy text on it,
   and the darkened gold roles (accent-text, accent-border) wherever gold has to read on white.
   The values below are a copy of the roles this store uses, under the same names; no other hex
   value appears outside this block. Inter (SIL OFL 1.1, assets/fonts/OFL.txt) as in BQT-Mobile-UI. */
