   Composes cleanly: dark+default, dark+uf, light+default, light+uf, ...

   Tokens defined here are CONSUMED by all new primitives below
   (.ds-*) and by any template that references them. Existing
   .atk-* and legacy classes continue to work via the older tokens
   in base.html — those are aliased into the new names below.

   To add a new tenant theme:
     1. Add a [data-scheme="<name>"][data-theme="dark"] block in
        base.html with overrides for --accent, --accent2, --grid.
        (Keep neutrals tied to data-theme so accessibility holds.)
     2. Done — every component picks it up automatically.
