+ * `autosaveId`. The keys look like `panel-group-react-aria<n>-:<rid>:`
+ * and accumulate without bound across sessions until they exhaust the
+ * ~5 MB origin quota and break subsequent `setItem` calls.
+ *
+ * The library no longer behaves this way, but existing users still carry
+ * the residue. Evict it (plus the orphaned `panel-run-parent-v2` key from
+ * the v2→v3 autosaveId bump) once on load.
