galaxy-game/ui/frontend/tests/game-shell-sidebar.test.ts

// Component tests for the Phase 10 in-game shell sidebar. Validates
// the default selected tab, the Calculator / Inspector / Order
// switching, the empty-state copy that matches the IA section, the
// `?sidebar=` URL seed convention used by the mobile bottom-tabs,
// and the Phase 13 selection-driven planet inspector content.
