Module overlay 

The Overlay trait and its supporting types — the contract every editor overlay (note browser, Saved Searches modal, or dialog) implements so the OverlayHost can route input / app-messages / render to it uniformly.

Enums

OverlayKind

Identifies which overlay is active — used for toggle, focus label, and hints.

OverlayMsg

Outcome of routing an AppEvent to the active overlay. Overlays never request their own dismissal here: dialogs close by emitting the AppEvent::CloseOverlay event, which the editor handles separately.
