/* PIP-OS theme definitions */

/* Categorical chart palette — validated (CVD-safe, contrast-checked) against
   each theme's own surface via the dataviz skill's validator. WHITE/GREEN/AMBER
   share the dark-surface steps (their --bg is always near-black); PAPER uses
   the light-surface steps since its --bg is a light cream. Slot order is the
   CVD-safety mechanism — never reorder or cycle past 8 without re-validating. */
