	Generated: $(date)
	Commit: ${{ github.sha }}
	Branch: ${{ github.ref_name }}

	## Files Generated

	### Preview Renders
	- Main assembly view
	- Front view
	- Side view
	- Top view
	- Module examples (5 modules)

	### Animations
	- 36 animation frames
	- Animation GIF (if ImageMagick available)

	### CNC Files
	- assembly.png (3D render of complete assembly)
	- cnclayout.svg (2D layout for CNC cutting)

	## Validation Results

	✓ All OpenSCAD files validated successfully
	✓ Main design file compiled without errors
	✓ All module files syntax-checked

	## Next Steps

	1. Review rendered images in the artifacts
	2. Use cnclayout.svg for CNC plasma cutting
	3. Use animation frames to create videos
	4. Export DXF files for individual parts using export_all_cnc_parts.sh
