Struct UiAtlasMap 

pub struct UiAtlasMap(pub HashMap<AssetUUID, AtlasRect>);

Per-frame UI atlas lookup: texture UUID → allocated AtlasRect.

Maintained by the UI agent (which owns the atlas allocator) and passed to the UI render lane through LaneContext. Replaces the old in-place ExtractedUiNode.atlas_rect mutation, which violated the immutable LaneBus invariant once the bus replaced UiSceneStore.

Tuple Fields

0: HashMap<AssetUUID, AtlasRect>
