/*
 * ONE theme for every restaurant and every screen (guest, billing counter, kitchen, owner, manager). These are the platform's own colours: a restaurant cannot recolour them,
 * and no role has an accent of its own. To change the look, change the tokens here and nowhere else. (Status colours ok / warn / bad / info are meanings, not theme.)
 * The only thing a role changes is the kitchen's dark SURFACE (a kitchen display is read from across a room); it keeps the same brand accent.
