- Per-signal, per-plot vertical scale state (sigVScale keyed by plotId:signalKey)
so the same signal in two plots has fully independent vscale config
- Active signal redrawn on top of all series with 2× line width for clear
visual identification; badge click toggles selection and opens/closes the
embedded vscale toolbar (click same badge again to deselect)
- Vscale configurator moved from floating popup to a slim toolbar strip
anchored inside the plot card, with an × close button
- Trigger dropdown shows one entry per array signal with [0…N-1] label;
opening it shows an index-picker dialog to choose the element
- Zoom resampling: when server returns no data for a zoomed range, fall
back to the local circular buffer instead of returning empty arrays

Replace fragile zoomGuard boolean with userInteracting flag so that
programmatic scale updates (rolling window, resize, fit) never lock
p.xRange. Only genuine mouse drag or scroll-wheel events on the uPlot
canvas set userInteracting=true and allow onZoom to freeze the view.
Also move stale-xRange detection out of the needsRedraw gate so that a
plot whose circular buffer has scrolled past a frozen zoom range
automatically returns to rolling-window mode every frame, fixing the
second bug where data disappeared as the buffer wrapped.
