/* landing.css — the shared stylesheet for blitzmate.co's SEO landing pages
   (quick 261007-landing-play-chess-online).
   See docs/website/LANDING-PAGES.md for how to add a page that uses it.

   WHY THIS IS A FILE AND NOT AN INLINE <style>. index.html, support.html,
   delete-account.html and the generated legal pages each inline their own copy
   of the house :root. That is right for them: each is a one-off, and the legal
   pages must render with no second request at all. Landing pages are the
   opposite case by design — there will be several, each a copy of the last — and
   a fourth and fifth inlined copy of the same 70 lines is exactly what makes a
   template rot out of sync with the design it came from. One file, long-cached
   (web-invite/vercel.json), same origin, so the [origin] guard is untouched.

   Type colours follow the standalone-page rule, which is NOT a preference:
   --text with an underline for body links, because #FF5A4D fails WCAG AA at 15px
   on this background (TOKENS, Brand accent). The accent survives as a solid fill
   behind --bg text on the CTA, where contrast runs the other way, and in the
   13px footer. Do not promote it to body text. */
:root {
  /* House :root — byte-identical to support.html:20-29 and
     generate-privacy-html.ts:103-112. Never redefined. */
