/*
 * The public site's one stylesheet (build-plan Phase 51; spec §12.2). Named by
 * hand and served at the hour tier, so a deploy can pair it with a cached page
 * for up to an hour: keep every change to it one the previous page survives.
 *
 * The colours are the web client's tokens (web/src/styles/tokens.css), copied
 * rather than shared, because the site does not build with the client.
