/**
|
|
* @file PlotGrid.h
|
|
* @brief Resizable grid of PlotWidgets realising the selected PlotLayout.
|
|
*
|
|
* Built from nested QSplitters (rows of columns) so cells are user-resizable,
|
|
* mirroring the ImGui draggable separators. Holds up to kMaxPlotSlots plots,
|
|
* fans out the 60 Hz tick / model / pause notifications, and drives the
|
|
* history navigation (live ⇄ stored-X) for all visible plots.
