Same technology as ProfilePlotWidget — plain QWidget + QPainter — because pixel-exact column alignment with the profile above is the whole point: the pane adopts the profile's left/right gutters and its virtual-chainage x quantity, and the two stay locked through zoom/pan via setVisibleXRange() / visibleXRangeChanged().

Data model: the host dialog pushes fully-resolved Tracks (title, pen, per-source sampled profiles). The widget owns no fetching, no layers, no attribute knowledge beyond node-vs-link rendering:

• node attributes draw a polyline through the value at each node's virtual x;
• link attributes draw one horizontal segment per link (a link's flow / velocity is a single value over its length — interpolating across nodes would invent data), with no vertical connectors.

Animation: setCurrentPeriod() indexes the pre-fetched arrays — nothing is fetched per frame (fetch-once / index-per-frame, the 2D-profile pattern).
