/*
 * The dusk world, on the web.
 *
 * Palette copied from `apps/mobile/src/theme.ts`. There is no import path from TypeScript to
 * a stylesheet, so if the theme moves, move these — the app and its marketing site being
 * different colours is the sort of thing nobody files a bug about and everybody notices.
 *
 * No web fonts. The app's accent face is Iowan Old Style, which ships with macOS and iOS and
 * is not licensed for webfont serving; the stack below lands on it where it exists and on a
 * reasonable old-style serif everywhere else. Nothing here fetches from another host, which
 * also means the pages work on a locked-down network and load in one round trip.
