Refactoring:
- Extract FULLSCREEN_QUAD_VS shader (reused in mipmap, display, layer viz)
- Add helper methods: getDimensions(), setVideoControlsEnabled()
- Add section headers and improve code organization (~40 lines saved)
- Move Mip Level selector to bottom of left sidebar
- Remove "Features (p0-p3)" panel header
Features:
- Add video loop support (continuous playback)
Documentation:
- Update CNN_V2_WEB_TOOL.md with latest changes
- Document refactoring benefits and code organization
- Update UI layout section with current structure

- Align layer naming with codebase: Layer 0/1/2 (not Layer 1/2/3)
- Split static features: Static 0-3 (p0-p3) and Static 4-7 (uv,sin,bias)
- Fix Layer 2 not appearing: removed isOutput filter from layerOutputs
- Fix canvas context switching: force clear before recreation
- Disable static buttons in weights mode
- Add ASCII pipeline diagram to CNN_V2.md

- Rename 'Static (L0)' → 'Static' (clearer, less confusing)
- Update channel labels: 'R/G/B/D' → 'Ch0 (R)/Ch1 (G)/Ch2 (B)/Ch3 (D)'
- Add 'Layer' prefix in weights table for consistency
- Document layer indexing: Static + Layer 1,2,3... (UI) ↔ weights.layers[0,1,2...]
- Add explanatory notes about 7D input and 4-of-8 channel display
- Create doc/CNN_V2_BINARY_FORMAT.md with complete .bin specification
- Cross-reference spec in CNN_V2.md and CNN_V2_WEB_TOOL.md

Features:
- Right sidebar with Layer Visualization (top) and Weights Info (collapsible, bottom)
- Activations mode: 4-channel grayscale views per layer (Static L0 + CNN layers)
- Weights mode: Kernel visualization with 2D canvas rendering
- Mode tabs to switch between activation and weight inspection
- Per-layer texture storage (separate from ping-pong compute buffers)
- Debug shader modes (UV gradient, raw packed data, unpacked f16)
- Comprehensive logging for diagnostics
Architecture:
- Persistent layerTextures[] for visualization (one per layer)
- Separate computeTextures[] for CNN ping-pong
- copyTextureToTexture after each layer pass
- Canvas recreation on mode switch (2D vs WebGPU context)
- Weight parsing with f16 unpacking and min/max calculation
Known Issues:
- Layer activations show black (texture data empty despite copies)
- Weight kernels not displaying (2D canvas renders not visible)
- Debug mode 10 (UV gradient) works, confirming texture access OK
- Root cause: likely GPU command ordering or texture usage flags
Documentation:
- Added doc/CNN_V2_WEB_TOOL.md with full status, architecture, debug steps
- Detailed issue tracking with investigation notes and next steps
Status: Infrastructure complete, debugging data flow issues.
handoff(Claude): Layer viz black due to empty textures despite copyTextureToTexture.
Weight viz black despite correct canvas setup. Both issues need GPU pipeline audit.
