/* Classroomcompass — website.
 *
 * Palette is docs/branding.md. Values are copied rather than imported because
 * this site has no build step, but they are the same hexes lib/theme.dart uses.
 *
 * Unlike the app, this commits to the guide's indigo hero. The app could not:
 * it puts tab bars and text actions inside its bars, and Material resolves
 * those colours from the scheme. A marketing page has no such constraint, so
 * here the palette gets what it actually asked for.
