- Correct hub1 port map: A is the left arm, C is the head tilt.
- Arms: L2/R2 raise proportionally, L3/R3 lower at reduced power.
- Head turn onto L1/R1, head tilt onto d-pad left/right, body lift onto
d-pad up/down. All move while held.
- Square is now the panic stop; Cross toggles 50/100% track speed.
- Circle and Triangle toggle two GPIO LED circuits on pins 25 and 26.
- Latching controls are edge-detected; frames arrive at ~50Hz so a held
button would otherwise toggle continuously.
