Update: FilySystemBackend supports "dynamic" asset bundles - updated store overlay pages to use it Was able to succesfully load up Abyss store page, observed no stutters. Confirmed with memory profiler that abyss textures were loaded only on entering the page, but discovered that they remain afterwards despite unload (as they're still owned by asserscenes.bundle somehow) despite ui/store.bundle being unloaded. That'll be next. Tests: used both normal and bundle backends in editor and navigated to Abyss page. Built a debug client and navigated to Abyss page, took snapshots. Built Release client to see if stutters are present.
