/* ============================================================================
   GILT & PARCHMENT - luxury/artisanal house theme for the coin / bullion /
   jewellery storefront.

   Aesthetic: a fine dealer's catalogue. Aged ivory parchment stock, espresso
   ink, and worked gold used like the metal the store actually trades - set,
   not splashed. Fraunces (variable serif) carries every display line and the
   italic flourishes; Inter sets body, UI, and the letter-spaced small-caps
   labels. Hard right angles, mono type and poured-concrete shadows are gone:
   hairline clay rules, generous air, soft warm shadows, and a restrained gilt.

   Loaded after bootstrap.css (see Bundle.config), so everything here is an
   intentional override of Bootstrap 5 defaults. The CSS variable *names* are
   held stable - pages reference var(--gold), var(--concrete-300), var(--cast)
   etc. inline - only their values changed when the theme moved from the old
   concrete-brutalist scheme. Tokens first, then base, then component
   overrides, then theme utilities, then carried-over functional bits.
   ============================================================================ */
