/* theme.css — the ONE place tokens live. v134v (design spec, 2026-08-26).
   Every surface links this. No page may re-declare a token: the five-times-
   copied palette was the CSS incarnation of the duplicated-logic disease
   CLAUDE.md documents. Data-series colors inside charts are NOT tokens —
   chrome gets the brand, data keeps its contrast. */
