   Extracted from the homepage design system (index.html) so every SEO/landing
   page shares one source of truth. Light-only, matching the existing brand
   identity. Homepage-specific widgets (hero ledger, security panel) stay inline
   in index.html; this file carries the tokens + components new pages reuse,
   plus a few components those pages introduce (breadcrumb, prose, callouts,
   comparison/check tables, answer blocks, CTA band).
