/* marketing-site/styles.css
   Kapslo, 2026 redesign.
   Palette = the app's own tokens (src/theme.ts) plus the icon's capsule amber,
   so the site and the app read as one product:
     teal   = brand + primary actions
     amber  = the capsule half, used as a highlighter, never for text on paper
     violet = AI / Premium, and nothing else (same meaning as the in-app accent)
     red    = over the limit / myth verdict, and nothing else
   Type: Bricolage Grotesque (display), Geist (text), Geist Mono (doses, numbers).
   Light and dark themes via prefers-color-scheme; all colour lives in tokens. */
