 * The palette is the app's own (app/lib/theme/watchtower_theme.dart), so the

 * because the app's default theme is dark, then re-pointed for light.
 *
 * No web fonts, no CDN, no framework: the site is served from the project's own
 * Pages artifact, and a privacy-forward app should not have a third party in
 * the critical path of its own homepage.
