   1. TOKENS  — the only place colors are defined.
   theme.json mirrors these for the editor; keep both in sync.
   LIGHT IS THE DEFAULT. :root holds the dark values, and the block below
   overrides them whenever data-theme is anything other than "dark" —
   including when the attribute is absent, so light survives JS being off.
