   eargs — bespoke stylesheet (no framework, token-based).
   Light theme is the default; a safe dark theme is applied via
   @media (prefers-color-scheme: dark) purely through CSS variables, so
   every component re-skins itself with zero duplicated selectors.
   All blended tints are precomputed as variables (no color-mix()) so the
   UI renders identically on old and new engines.
