  Outcomes By Page — marketing site.
  Brand tokens: primary purple #7C3AED (~5.7:1 on white), deep ink #24143F (13:1+ on
  white), soft surface #F4F0FF. One purple, used consistently for links, buttons, and
  accents; ink carries body text so contrast never depends on the accent hue.
  Typography scale below is duplicated (not shared) in public/app/app.css — this site and
  the dashboard are served from separate static roots. Keep both in sync by hand.

/* Self-hosted (public/site/vendor/fonts, OFL-licensed) rather than a Google Fonts request,
   so this page keeps making zero third-party network calls — same reasoning as vendoring
   Bootstrap. Each file is the variable-font build, so one file covers every weight from
   100-900 (and therefore "semibold" at 600) rather than needing a static file per weight. */
