Reverts the LOD switching (0469b256). Rendering lod1/lod2 on zoom-out produced
WebGPU validation errors (invalid bindGroup_object) on real-GPU browsers — not
caught earlier because headless Chromium falls back to the WebGL2 backend, so
the WebGPU path was never exercised. The viewer returns to loading the baked
KTX2 lod0 (still the 22MB->12MB win). LOD switching to revisit with a real-GPU
test loop and on-demand loading instead of preload-all.
