/* flapfit.com — the app's own look, carried to the web.
 *
 * Every value here is a token from app/lib/screens/theme.dart (S, G) or
 * app/lib/design/brand.dart, under the same name, so a change to the app's
 * palette has one obvious place to land here too. The rules that travel:
 *   - the ground is near-black, cooled a touch green (S.paper);
 *   - the shell has no accent of its own: colour belongs to the five games;
 *   - green appears only where it means alive (the streak);
 *   - Big Shoulders is the game talking (headlines, names, numbers),
 *     Archivo is everything you read.
