/* ==========================================================================
   BibleSlide design system — tokens, type scale and accessible base (Core).
   One source of truth for the public site, sign-in, dashboards and the /app.
   Loaded by Core on every front-end page, the sign-in pages and the app shell.
   Rules of use:
   - Components read semantic tokens (var(--brand-primary)…); never copy a hex value into a new component.
   - Everything here has zero specificity (:where) or is a custom property, so no existing component is overridden.
   - Colours of the official logo: royal blue, golden yellow, deep navy (checked on brand-logo.png: blue #0040A8–#0048B8,
     gold #D89818–#D8A020, navy #002870 — the tokens below are within that range, slightly lifted for screens).
   - Worship/presentation output (slides, projector, stage, themes chosen by users) does NOT use these tokens.
