Module context 

Stateless authoring time, design coordinates and optional shared computation.

Structs

CacheLimits

Entry-count and payload-byte allowance shared by the cache constructors.

RenderCache

Cloneable rendering cache shared by sessions and export workers. Each partition has its own entry and logical-byte allowance; external Arc pins and allocator overhead are not included. Computation runs outside cache locks.

SceneCache

Shared LRU storage for pure authoring computations, with optional byte accounting.

SceneContext

Immutable scene evaluation inputs in signed ticks and logical coordinates.

Enums

CachePartition

Independently bounded pure rendering-cache domains.
