 * ---- shadcn/ui semantic layer --------------------------------------------
 *
 * shadcn components are written against role tokens (`bg-background`,
 * `text-muted-foreground`, `border-input`, `ring-ring`) rather than against a
 * palette. This block is the adapter: it gives those roles values drawn from
 * the ink/volt scales above, so an unmodified component pasted from the
 * registry already looks like this store.
 *
 * ONE TRAP WORTH NAMING: shadcn's `--accent` is not a brand accent. It is the
 * subtle surface behind a hovered ghost button or a highlighted menu row. It
 * maps to ink-100. The brand accent stays `--color-volt-*` and is applied
 * deliberately — mapping volt here would turn every hover state neon.
 *
 * The store is committed to a light palette (`color-scheme: light`), so there
 * is no `.dark` block. shadcn's `dark:` utilities simply never match, which is
 * harmless and keeps the registry components paste-able unedited.
