/*
  FINE marketing site — shared stylesheet.

  Tokens live at the top as CSS custom properties on purpose: the palette
  below is the "Coral Pop" brand direction (see docs/brand.md — source of
  truth for every hex value here). Any future palette tweak should stay a
  variables-only change, not a find-and-replace across every page.

  Coral Pop personality: "confident optimist." Warm cream ground, coral
  accent spent deliberately (hero CTA, links, small moments), deep violet
  ink for text, teal as a secondary note. No external fonts/CDNs — system
  font stack only.
