+ * @file PlotWidget.h
+ * @brief Oscilloscope plot panel (custom QPainter), one per grid cell.
+ *
+ * Mirrors the ImGui PlotPanel: fixed +/-4 division Y space, wall-clock live X
+ * window, LTTB decimation, normal/digital/mixed normalization, A/B cursors,
+ * scroll/drag zoom + pan, zoom history, hi-res WS zoom + history zoom, and a
+ * trigger-capture view rendered in [-pre, +post].
