// Phase 29 component coverage for `lib/active-view/map-toggles.svelte`.
// The popover is a thin view of the `GameStateStore` runes —
// every control fires `setMapToggle` / `setWrapMode` on the store
// and reads the current state through `store.mapToggles` /
// `store.wrapMode`. The tests assert the wiring, the default
// rendering, and the popover lifecycle (open / Escape close).
