// Vitest component coverage for the read-only planet inspector.
// Each kind has a dedicated case so the per-kind field gating
// (which fields are present, which are hidden) is verified
// explicitly. The component is purely presentational, so the tests
// drive it with synthetic `ReportPlanet` literals — no store.
