// ===== Graph Tab =====
// Whole-run multi-sensor line chart (C# parity: tabGraph/chartData). Static
// snapshot recomputed whenever a file is loaded — not live-updating during
// a stream. RunChart adds wheel zoom, drag pan, and a visible-range
// min/max/avg strip. See specs/plans/2026-07-10-graph-tab.md and
// docs/adr/0003-pyqtgraph-for-multi-sensor-charts.md.
