L2.3 CAN Bus Transceiver: complete PCB layout

- Schematic: 12 components, 10 nets, ERC 0 (MCP batch_add_components + connect_to_net)
- Board: 20x30mm 2-layer, JLCPCB DRC rules (0.15mm clearance)
- Placement: U1 SN65HVD230 center, J1 CAN bus right, J2 power left, split termination below
- Routing: Freerouting headless CLI, 44 tracks, 1 via, 13/14 nets routed
- GND copper pour F.Cu+B.Cu, 20 stitching vias, collision-checked
- DRC: 8 violations (3 courtyard overlap + 5 silk edge clearance - cosmetic only)
- Gerbers exported (8 layers + drill)
- SVG exported for review
