OptionalkindWhat the series is read as. uPlot draws every kind through an opaque

for it; set this when a custom path builder defeats that inference.
OptionalexcludeLeave this series out of MAIDR entirely.
Per-series options, set on the series itself as
maidr: { ... }or passed through MaidrUPlotOptions.series.
