Description
bands appears nowhere in src/.
A stream that has been min/max-decimated upstream (e.g. ~1 kHz sampled down to display rate) wants, per channel, a last-value line plus a filled min/max envelope — otherwise the decimation silently eats exactly the transients you decimated in order to keep.
In uPlot that is a band over two hidden series. It looks reachable through the uplot escape hatch (top-level array, replaces cleanly), but there is no first-class concept in SeriesConfig and nothing to carry the envelope alongside a TimeSeries.
Lower priority than #30 — probably escape-hatchable once per-series scales exist.

Research direction
Start in src/ by locating SeriesConfig, TimeSeries, and the uplot escape hatch described in the issue; inspect how per-series scales are represented and how top-level uPlot options are replaced. Done means a first-class per-channel min/max envelope can accompany a TimeSeries, rendering a last-value line with a filled band over the hidden min/max series.
