   --------------------------------------------------------------------------
   Volvo Broad for display type. Near-black graphite base, white + blue as the
   primary voice, gold reserved for accents (numbers, marks, emphasis rules).

   Everything is tokenised in :root with a light-theme override block, so both
   schemes render from one sheet.

   LAW: content visibility is NEVER gated on JS. Scroll animation is additive,
   via `animation-timeline: view()` inside @supports. A frozen/snapshot renderer
   must still show a complete page.
