 * the `storage` event, and syncs other components in the same tab via an internal
 * registry. Returns `[value, setValue, remove]`.
 *
 * Values are JSON-serialized by default; pass a `serializer`/`deserializer` to
 * store raw strings (e.g. a theme name the no-flash script reads directly).
 *
 * Prefer the `useLocalStorage` / `useSessionStorage` wrappers unless the backend
 * is chosen at runtime.
