/*
 * oratioprayer.com: the Oratio app's look on the web.
 *
 * The colors, type, radii, and shadows are the app's own design tokens
 * (Oratio-Prayer-App: app/lib/theme/tokens.dart), so the site and the app
 * read as one thing: parchment pages, paper cards, the burgundy hero with its
 * gold kicker, Crimson Pro headings over Inter text. With the device in dark
 * mode the site takes the app's night theme (midnight blue, night gold).
 * The fonts are the app's (SIL Open Font License, assets/fonts/OFL.txt),
 * served from this site, so a page loads nothing from anyone else.
