/* Hearth, on the web.
 *
 * The colours are copied across from lib/theme/hearth_colors.dart in the
 * Heads Up repo, which is the only place in the app allowed to hold a hex
 * literal. If a token is retuned there, retune it here too — this file is
 * the one place on the site that knows what a colour is.
 *
 * Figtree is self-hosted rather than pulled from Google Fonts. A CDN link
 * would make a third-party request that the privacy policy would then have
 * to disclose, and it would cost the site the plainest true thing it can
 * say: that it loads nothing from anyone else.
