// Native routing targets in board-world millimetres (+X right, +Y up).
// These are PCB features; supplier symbols, pin maps and lands are untouched.
// PD pad exits are solved natively; MCU exits use native saved FanoutTracePaths.
// Every emitted path and via must pass the same independent copper/drill checks.
// Ground pins remain at their real component pads for native plane fanout.
// FanoutSolver requires component endpoints and cannot start at an escaped point.
// U1 EP pin25 has no imported thermal vias and requires a real ground escape.
// The twelve accepted imported vias belong to U4, U5 and U10 only.
// The native solver must clear peripheral pads and prohibit new via-in-pad.
