   PICKAXE PLAYER — landing page styles
   Token values are verbatim from the Pickaxe Design System project
   (tokens/colors.css, typography.css, spacing.css, effects.css, fonts.css),
   same source as the iOS bridge in DesignSystem/. Two adaptations for a
   static no-JS page:
   - dark mode keys off `prefers-color-scheme` instead of [data-theme='dark']
   - Inter is not imported (no third-party requests); the --font-sans stack
     falls back to the system face, which is what the app itself uses on iOS
   When a token changes upstream, update the matching line here.
