/* ─────────────────────────────────────────────────────────────────────────
   BACK-COMPAT ALIAS SHIM — do not add anything here.

   This file used to be the single flat token file. It is now a thin alias
   layer so the ~250 existing call sites keep resolving while they are
   migrated to the tiered tokens in tokens/. Every name below is deprecated:
   write var(--color-*) / var(--space-*) / var(--text-*) / var(--radius-*)
   in new code, and delete the alias once its last caller is gone.

   New tokens go in tokens/primitives.css, tokens/semantic.css or
   tokens/components.css. See docs/dev/web/design-system.md §3.
