Emulate a Nintendo Switch 2 Pro Controller over BLE (custom GATT + reverse-engineered pairing) so a real Switch 2 accepts it as a native controller and can be woken from sleep.
Boards of ESP-IDF programs described once as data: pins, buses and parts, each fact with where it comes from. The board is chosen once; the component sets its hardware up through the library of each part, and the program asks for what it needs by kind, never by the board's name. A build downloads only the libraries the chosen board needs.
