   TDM Blocks — design tokens (--tdm-* namespace)

   The package ships its OWN token set so it works standalone on any Concrete
   site. Blocks NEVER hard-code values — they reference var(--tdm-*). The Brand
   Kit dashboard overrides any of these at :root per site, re-skinning every
   block at once.

   Defaults below are seeded from the ARECH design-system-v1 (dark theme) as
   the first consumer; on a new site, set the Brand Kit and these are replaced.
   On ARECH you may also map a token to the live theme variable, e.g.
   `--tdm-color-accent: var(--orange);` so the library tracks the theme.
