/* =============================================================================
   Quiz-funnel renderer — Product A LOCKED LOOK.
   LIGHT · warm · photography-led. Big SOLID tap chips (neutral -> accent when
   selected). Thin dot progress spine. Big fluid variable-type question. NO
   dark-glass, NO backdrop-filter/blur (reserved for Product B; INP cost bites on
   cheap ad-traffic Android). One accent = the CLIENT's brand color, on the
   selected-option state + the single primary CTA ONLY.

   All color/space/type come from shared/ui tokens (var(--color-*) etc.) so a
   rebrand is one file. The ONLY per-client color is --funnel-accent, injected
   inline from theme.accent; it falls back to the token accent.
