/* ---- Theme tokens -------------------------------------------------------
   Dark is the default (:root). Light overrides via [data-theme=light].
   Every colour below is a token so the whole app recolours from here.
   Cardbase palette: ink-and-paper with a dusty-rose accent — deliberately
   distinct from its sibling fiber-kit (which is green/mustard). */
