/**
 * Raspberry Pi 5 — Velxio schematic board.
 *
 * Authored from scratch (not traced from RPi Foundation art); the layout
 * is the publicly-known PCB topology: BCM2712 SoC centre, RP1 southbridge
 * to its right driving the I/O, 4× USB-A + 2.5 GbE on the east edge,
 * USB-C power + dual micro-HDMI on the south, 40-pin GPIO header on the
 * north, dedicated power button on the west, PCIe FFC connector on the
 * underside, fan header to the north-east of the SoC.
 *
 * The 40-pin GPIO header is electrically identical to every Pi from
 * the 1B+ onwards, so the pin coords mirror RaspberryPi3Element /
 * RaspberryPi4Element byte-for-byte — wires snap to the same physical
 * positions when a user swaps boards.
