// USB-C 6-pin SMD power-only receptacle (e.g. GCT USB4085-GF-A)
// Body ~7.3×8.94mm, mid-mount. Pin map for power-only USB-C 6-pin:
//   1=GND  2=VBUS  3=CC1  4=D+  5=D-  6=VBUS (paired)
// Some 6-pin power-only variants use:
//   1=VBUS  2=GND  3=CC  4=D+  5=D-  6=SBU  (varies by vendor)
// Per GCT USB4085 datasheet pin assignment we use pin labels via pinLabels in the chip.
