/**

* @file TriggerPanel.cpp
|
||||
* @brief Trigger configuration bar — hub-side trigger semantics.
|
||||
*
|
||||
* The trigger runs in the C++ StreamHub: this panel only edits the config
|
||||
* (signal/edge/threshold/window/pre%/mode), sends setTrigger + arm/disarm/
|
||||
* rearm/trigStop commands, and reflects the hub triggerState broadcasts.
