  The one stylesheet for every page. Body text uses the phone's own fonts, so a page costs no font
  download on 3G. Only the wordmark loads a font: two subsets holding its seven letters, 4 KB in all
  (OPEN-116). Brand colours: perfcent repo, .claude/skills/frontend/references/brand.md. Marketing is
  the green context: green arc, dim cobalt stems. Buttons are cobalt, because white on the brand green
  is too faint to read.
