+Mode `2` selects 32-bit RGBW output. On every released RP2040 firmware up
+to and including `0x0C` it turns the LEDs off instead: the switch enables
+the output and then falls through into the disable case.

+[The fix](https://github.com/badgeteam/mch2022-firmware-rp2040/pull/22) is
+on `master` and is not in a release yet, so a badge you did not build the
+firmware for yourself still has this. Use mode `1` there.
