/* Raw lwIP sockets, for the UDP video sender.
 *
 * esp-idf-svc has no UDP socket type, and its HTTP server is TCP-only, which is
 * exactly the transport that measured badly on this board: the sensor produces
 * ~22 fps at VGA, but a TCP MJPEG stream over the same WiFi link managed ~2 fps
 * while using less than 1% of the available bandwidth. The link was idle and the
 * frames were stuck behind TCP head-of-line blocking, waiting on a retransmit
 * timer. Sending the same JPEGs as independent datagrams removes that entirely.
 *
 * Including lwip's own header is all that is needed: it declares the socket calls
 * and the real `sockaddr_in`. Declaring them here instead would both duplicate the
 * declarations (a hard error) and produce an opaque struct that shadows the layout
 * bindgen generates from the real header. */
