   Branded Discovery-Call Booking — design system (§5, enforced)
   Every color traces to a §5 token. Accent (#B25A32) is used on CTAs ONLY.
   Contrast note: white-on-#C1653A measures 4.05:1 (fails 4.5:1), so per §5 the
   CTA accent is darkened to #B25A32 = 4.77:1 white-on-accent / 4.66:1 as text.
   No drop shadows. System fonts only (no CDN). Mobile-first.
