   ideaboxd - shared site stylesheet
   --------------------------------------------------------------------------
   Extracted verbatim from the homepage's inline <style> block, which in turn
   lifts its tokens from src/constants/theme.ts. The homepage keeps its copy
   inline (one request, fastest first paint on the entry page); the SEO landing
   pages link this file so they share one cached stylesheet between them.

   If you change a token or a product-visual component, change it in
   landing/index.html first, then re-extract:
     python3 - <<'EOF'
     import pathlib
     s = pathlib.Path('landing/index.html').read_text()
     css = s.split('<style>',1)[1].split('</style>',1)[0].replace("url('./fonts/", "url('../fonts/")
     # keep this header, then write css + the SEO-only rules at the foot
     EOF
