florian.berthold d43c7976ad Add panel-to-PCB mounting system with M3 standoffs 
Panel alignment:
- PCB offset 10mm from panel top
- Component holes aligned: OLED@25mm, jacks@45mm, button@58mm
- 4x M3 standoff holes at corners (5,5), (35,5), (5,75), (35,75)

Updates:
- Panel SVG and spec aligned with PCB layout
- Mounting holes added to PCB (Edge.Cuts layer)
- Regenerated Gerbers with mounting holes
- Updated autoroute.py to add mounting holes automatically

DRC: 0 unconnected, 7 cosmetic errors (courtyard overlaps)

florian.berthold ccb833fdc3 Add Gerber manufacturing files and export script 
Generated files:
- gerbers/: All Gerber layers, drill files, pick-and-place CSV
- SN-L00-gerbers.zip: Ready for upload to PCB fab
- scripts/export_gerbers.sh: Regenerate with one command

Layers: F.Cu, B.Cu, F/B.Paste, F/B.Silkscreen, F/B.Mask, Edge.Cuts

florian.berthold 1ae49dc1bb Add 8HP layout with fully automated routing pipeline 
- Update PCB to 8HP format (40x100mm) with v2 component placement
- Add automated routing scripts (autoroute.py runs full pipeline headlessly)
- Update panel spec and SVG for 8HP dimensions
- Board routes in <1 second with 0 unconnected pads

Scripts:
- autoroute.py: Full CLI pipeline (place → export → route → import → DRC)
- autoroute_full.py: Same pipeline for KiCad scripting console
- place_8hp.py: Component placement only
- route.sh/freeroute.sh: Routing helpers

florian.berthold cd337b8718 Add Freerouting autoroute script 
- autoroute.sh: Downloads and runs Freerouting in batch mode
- Updated README with complete PCB layout workflow
- Script handles DSN→SES conversion automatically

Usage: Export DSN from KiCad, run ./autoroute.sh, import SES

florian.berthold a8e63aa45c Fix PCB file format and add placement script 
- Fixed KiCad 8 PCB file format (text rotation syntax)
- PCB now loads correctly with board outline and labels
- Added Python placement script for KiCad scripting console
- Updated PCB_LAYOUT.md with quick start instructions

Next step: Open in KiCad, run Update PCB from Schematic,
then use Freerouting or manual routing to complete traces.
