   LABBIE — SEO LANDING PAGES (marketing surfaces)
   Shared design system for the public, indexable landing pages
   (/ai-website-generator, /small-business-website-builder,
    /startup-website-builder, /ai-landing-page-builder).

   Reuses the homepage's visual DNA verbatim — cream background,
   white cards, ink text, the two-tone gold brand accent,
   Geist (sans) + Fraunces (serif) — but as a NORMAL, scrollable,
   fully responsive content page (not the homepage card-state
   machine). The homepage itself is untouched.
