// Phase 29 coverage for the categories + planetDependents maps that
// `reportToWorld` now returns. The map view consumes both to feed
// `RendererHandle.setHiddenPrimitiveIds`: categories drive the
// per-category toggle, planetDependents drive the cascade (planet
// hidden → markers + in-space + incoming groups flying to it hide
// together).
