Gamepad players expect stick X = turn; the pod-faithful default maps it
to torso twist, and the pedal pair couldn't take a single signed axis.
New bindings channel "Turn": a signed composite that decomposes into
the pedal pair at the RIO publish (+ = right pedal, - = left), ADDING
to direct pedal bindings so mixed rigs compose, clamped 0..1 per pedal.
The default bindings.txt stays pod-faithful and documents the
twin-stick alternative inline:
padaxis LX axis Turn
padaxis RX axis JoystickX
Also covers the HOTAS ask (any signed axis can now drive turning).
Verified: regenerated defaults carry the doc lines; a twin-stick-edited
bindings.txt parses and boots clean. Awaiting live pad verification.

// Maps PC keyboard keys and XInput pad controls onto the pod's abstract

// control surface: RIO button addresses (buttonGroup elements), MFD keypad

// units, and the five analog channels (Throttle, JoystickX/Y, Left/Right
|
