   SURFACE TEXT SCOPING
   Every element that renders as a light "card" surface (cards, headers, nav,
   modals, sheets, inputs, toasts, list items, calendar cells, stat tiles)
   re-declares the text tokens to their dark, on-cream values. Anything NOT
   inside one of these keeps the root (light, on-dark-canvas) values above.
   This one rule is what lets the whole app flip from a light-on-light theme
   to a dark-canvas/cream-card theme without editing every screen by hand.
