15//! ECS maintenance — drains the queued cleanup / vacuum work each frame.
16//!
17//! Replaces the previous hardcoded `gw.tick_maintenance()` call in the
18//! engine tick. The [`EcsMaintenance`] state lives in the
19//! [`ServiceRegistry`] (inserted at engine init) so the system can fetch
20//! and tick it without any wiring.
