/*
 * Shared styles for the Ditto public site.
 *
 * Tokens are copied from the app's `src/index.css` so the two read as one product. They are copied
 * rather than imported because this site deploys separately from the app and has no build step —
 * see `site/README.md` for why it is hosted apart from `dittomatch.app` at all.
 *
 * No fonts are fetched. The display face is whatever serif the reader already has, in the same
 * order the app asks for, so a legal page renders instantly and offline and pulls nothing from a
 * third party — which is a small privacy claim the privacy policy itself makes.

   * 3.56:1 behind the white button label — both under the 4.5:1 that normal-size text needs to pass
   * WCAG AA. It is fine in the app, where it is mostly a large surface rather than a word you have
   * to read. Here it is link text on a legal page, so it is darkened to 5.07:1 and the button to
   * 5.41:1. Dark mode keeps the original blush, which already measures 6.72:1 on #1a1715.
