Description
Previously, each chunk maintained its own registry mapping chunk paths to IDs for preloading, reducing string usage to save space. However, this registry was recreated for every chunk, even though a shared utility handled the actual preloading—which seemed like a more suitable place for this logic.
With this change, the chunk path-to-ID mapping is centralized in the shared preload method, eliminating repetitive chunk registries. I expect to see minor size improvements in apps that produce many chunks.
