 * Helper for the wave-3 `as=`/`dynamic()` element migration: resolve `class` / `style`
 * from a Base UI component's `props` against the live state accessor and
 * return a plain object with reactive getters suitable for `mergeRootProps`.
 *
 * Both keys may be raw values OR functions of state — the functions are
 * called inside the getter so they re-run on every reactive dependency
 * change. Returning `undefined` is fine; `mergeRootProps` treats undefined
 * as "absent" so internal defaults still win.
