VulkanDevice

Remarks

Handles index tables this object owns. Nothing here is finalisable and nothing is reference-counted by the collector: a GPU object's lifetime belongs to the renderer, and destruction is deferred by FramesInFlight frames so that a resource released while the GPU is still reading it stays alive until it is not.

Recording is thread-safe; creation and destruction are serialised by a lock. That split is deliberate — command recording is the hot path a renderer parallelises, and resource creation is not.
