 * Every colour here is copied from `lib/core/theme.dart` — Coach Sultan's
 * own palette, near-black carrying one bright yellow, the same values the
 * app ships. `sites/test/tokens_test.js` reads both files and fails if a
 * shared colour drifts, so this file is not a sketch of the app's theme;
 * it is the same theme.
 *
 * Dark is the default because the coach's programme file is black and both
 * sites are built from it. Light exists only for the dashboard, which is a
 * tool someone sits in front of all day; the public site never offers it.
