galaxy-game/ui/frontend/tests/inspector-ship-group-dismantle-confirm.test.ts

// Vitest coverage for the Phase 20 dismantle confirmation. The
// inspector requires an explicit second click ("colonists die") when
// the player tries to dismantle a colonist-laden group over a
// foreign planet — engine rule reference:
// `controller/ship_group.go.shipGroupDismantle:177-179` (over a
// foreign planet, `UnloadColonists` is not called and the cargo is
// lost).
