     Atlas Visual Language — single source of truth.
     Dark-Atlas is the dominant theme; light tokens redefine the same
     semantic names in the light @media block. Components consume only
     the semantic --bg/--fg/--accent/--err etc. — never the raw hex.
     If you tune tokens, tune all four CSS files in the same diff.
