/**
 * `ContextMenu` characterization (Phase F5a).
 *
 * Drives the menu via `usePlayerStore.openContextMenu(...)`, asserts on
 * the rendered items + their click → store-action wiring. Avoids deep
 * snapshots — tests survive a refactor that re-orders or re-styles the
 * markup as long as the menu items + their handlers stay observable.
