Second radio (wlxd8ec5e2faa8c, RTL8822BU/rtw88), same VanLink SSID+PSK, ch6 HT20, bridged into br0 next to the 5GHz AP. Runs as its own hostapd instance + own watchdog so a USB wedge on one radio never darkens the other; van-ap-watchdog now takes conf path + unit name as args (defaults unchanged). rtw88.conf disables deep power-save (rtw89 gotcha analog) and the driver's USB2->3 self-upgrade (USB3 noise in the 2.4GHz band — note: dongle currently sits in a USB3 port, so it still enumerates SuperSpeed; move to a USB2 port if 2.4GHz range disappoints).
