// SEN62 has snap features, not screw holes. These four NPTH holes mount
// the PCB to internal base-wall ledges. The sensor carrier mounts to the case floor.
// pcbY=-6 places global holes at (+/-18,-24) and (+/-18,19).
// The official STEP models and printable carrier are in mechanical/.
// Same horizontal manufacturer CAD, carrier and tie paths as assembly.circuit.tsx.
// Sensor upper envelope is exactly 4 mm below the PCB underside.
