  Token values are mirrored from the Vespers app's
  `frontend/src/styles/tokens.css` so this site reads as part of the same
  family. Names are kept identical on purpose — if the app's palette moves,
  the diff to apply here is obvious.

  The app resolves dark mode via `[data-theme="dark"]` (set by its
  ThemeProvider). This site has no JS, so it follows the OS setting via
  `prefers-color-scheme`, which is what an app user on the default "system"
  theme sees anyway.
