Images no longer load textures eagerly on creation. Instead, the culling ticker checks viewport proximity every 200ms: - Load margin: 1x screen size beyond viewport (preload before visible) - Unload margin: 2x screen size (hysteresis prevents thrash during pan) ImageSprite changes: - Constructor no longer calls loadTexture() — deferred to culling system - New unloadTexture() restores placeholder and frees GPU memory - Exposed texture getter for clipboard resolution detection - loaded field now public for culling system to check state This should allow hundreds of images without GPU OOM, since only nearby textures consume GPU memory at any time.
