// Real camera source backed by the Allied Vision Vimba X SDK (VmbCPP). Opens the
// cameras in CameraConfig and applies the on-camera imaging settings in-session.
//
// Two acquisition modes, chosen with setAcquisitionMode() before start():
//   TRIGGERED (default) - TriggerMode=On + TriggerSource=Software. acquireFrame()
//     fires one TriggerSoftware and returns that frame, so the image belongs to the
//     waypoint that asked for it and its exposure can be set deliberately.
//   FREE-RUN - a paced low-rate stream; trigger() hands over the latest complete
//     frame, restarting acquisition if the stream has stalled. Kept as a fallback.
// Encode/save lives in ImagePipeline; quality gating lives in GatedCameraSource.
