// Curated palette for Group cards. Colors are hand-picked and spaced evenly
// around the hue wheel so no two are near-duplicates and none clash, per the
// "vibrant colors from the same aesthetic family" requirement. Stored as a
// palette *key* on the Group record (not a raw hex) so this list can be
// retinted centrally without a data migration.
//
// Each color has a slightly deeper/less-saturated `dark` variant so a thick
// border doesn't glare against a dark background.
