[asdolo]

Summary

• Each button assigned Gestures keeps its own up/down/left/right/click map (Options+-style), instead of one shared profile-wide Gestures section.
• Legacy flat [Gestures] profiles migrate by copying the shared map onto every gesture-trigger button.
• Assigning Gestures to a button for the first time seeds that button from device defaultGestures.

Test plan

• Assign Gestures to two buttons; change a direction on one — the other must stay unchanged
• Restart app / reload profile — per-button bindings persist under [Gestures/<buttonIndex>/…]
• Open an older profile with flat [Gestures] keys — both gesture buttons still work, then diverge after editing
• logitune-tests filters for *Gesture*, ProfileEngine.*, DeviceModelTest.*Gesture* pass
