  Shared by every page under site/. Plain CSS, no build step: Caddy serves this

  The palette is the desktop app's (client/ui/DESIGN.md) so a player moving
  between the app and this site sees one product: charcoal surfaces, the amber
  T-side accent, the CT blue as the second voice. System fonts on purpose -
  a web font from a third-party CDN would hand every visitor's address to it.
