2026-06-28 — session end — Day 2

• Stopped with DRC at 109 errors / 6 unconnected (was 188 / 15)
• Matrix + RGB chain + power zones mostly routed; diode-to-switch fixes landed
• Blockers: +3V3/GND B.Cu pour islands (hotswap holes split copper); GND stub ~91,90 at D18; U1 pin13 GND
• DRC (68,29) is zone anchor, not island location — use Zone Manager preview + jump to 91,90 for GND trace
• Next: stitch traces, fix D18 GND, U1 GND, Edge.Cuts, M2 holes, hole clearance 0mm, Gerbers
