        With a USB dongle present the two jobs split across radios, and the
        assignment is deliberate:

          - the **AP stays on the built-in** radio. Not every USB dongle's
            driver supports AP mode at all, while the Pi's on-board chip
            reliably does, and 2.4 GHz is the band every phone can find.
          - the **client connection moves to the dongle**, which on a Pi Zero
            2 W is the only way to reach a 5 GHz network — the built-in radio
            is 2.4 GHz only.

        The payoff is that the AP never has to come down: hostapd keeps the
        built-in radio while the dongle joins, scans and roams independently.
