Detailed Description

Central resource cache and hot-reload coordinator.

AssetManager sits between game code and the raw byte-loading layer (IAssetLoader). It caches GPU textures so repeated calls to getTexture() never re-upload the same asset, and—when hot-reload is enabled—polls the loader for revision bumps every HOT_RELOAD_INTERVAL milliseconds, invoking registered callbacks so the game can react without restarting.

Ownership and lifetime

AssetManager is non-copyable. Callbacks registered via watch() are automatically cancelled when their WatchHandle is destroyed, which prevents use-after-free if a system outlives the manager.

Note

SDL_GPUDevice must outlive this object; the manager does not take ownership of the device pointer.
