       Light, document-feeling surface tokens for the drawer. Prefixed

       (e.g. the existing `--accent: 217 100% 56%` electric blue, used
       via Tailwind utilities everywhere). Same prefix family as the
       `--sidebar-*` tokens above. The drawer's component CSS will
       reference these via `var(--m-surface)` etc.
       Coexists with the dark app shell — the drawer is rendered on a
       light surface regardless of global theme.
