	measure)
78 min.	fix(cnn_v3/tools): zoom channel via WebGPU re-render + fill panel width	skal

80 min.	feat(cnn_v3/tools): click vignette to show enlarged channel below grid	skal

93 min.	feat(cnn_v3): add G-buffer visualizer + web sample loader (Phase 7)	skal
	C++ GBufViewEffect: renders all 20 feature channels from feat_tex0/feat_tex1 in a 4×5 tiled grid. Custom BGL with WGPUTextureSampleType_Uint; bind group rebuilt per frame via wgpuRenderPipelineGetBindGroupLayout. Web tool: "Load sample directory" button — webkitdirectory picker, FULL_PACK_SHADER compute (matches gbuf_pack.wgsl packing), runFromFeat() skips photo-pack step, computePSNR() readback + comparison vs target.png side-by-side. 36/36 tests pass. Docs updated: HOWTO.md §9, README, PROJECT_CONTEXT, TODO, COMPLETED. handoff(Gemini): CNN v3 Phase 7 done. Next: run train_cnn_v3.py (see HOWTO §3).
4 hours	fix(cnn_v3/tools): fix getElementById illegal invocation + auto-preload weights	skal
	- Bind document.getElementById in filmParams() to fix 'Illegal invocation' error - Add preload() that auto-fetches cnn_v3_weights.bin + cnn_v3_film_mlp.bin from workspaces/main/weights/ on init; skips silently if files not found - Add '↺ Reload from workspace weights/' button for manual re-fetch handoff(Gemini): cnn_v3 web tool fixed; serve from repo root via http.server
31 hours	feat(cnn_v3): HTML WebGPU tool (index.html + shaders.js + tester.js)	skal
	3-file tool, 939 lines total. Implements full U-Net+FiLM inference in the browser: Pack→Enc0→Enc1→Bottleneck→Dec1→Dec0 compute passes, layer visualisation (Feat/Enc0/Enc1/BN/Dec1/Output), FiLM MLP sliders, drag-drop weights + image/video, Save PNG, diff/blend view modes. HOW_TO_CNN.md §7 updated to reflect tool is implemented. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
