   MIGRATION SHIM.

   Every colour, font, spacing and focus value now comes from
   shared/tokens.css (copied here by tools/sync_tokens.py). The names below
   map this stylesheet's original vocabulary onto the shared semantic tokens so
   the rest of the file did not have to be rewritten. New code must use the
   semantic names directly; this block is a bridge, not an API.
