   Standalone stylesheet. Does NOT import the site's style.css —
   that file carries homepage-specific layout (fixed nav, bento
   grid, hero) that would fight a form. Instead the design tokens
   below are mirrored verbatim from style.css :root so the wizard
   reads as the same site.

   NO EXTERNAL REQUESTS. No @font-face, no font CDN, no remote
   images. Font families are NAMED (which makes no network request)
   with full system fallback chains, so a visitor who already has
   Inter / Crimson Pro / Space Mono installed gets an exact match
   and everyone else gets a close system equivalent.

   Type floors enforced: reading text >= 16px, labels >= 11px.
