Correct way of using an existing palette in a plot

[DamianoPellegrini]

#import "@preview/cetz:0.2.2"

cetz.canvas({
  import cetz.plot: plot, add
  import cetz.draw: translate, set-style
  import cetz.palette: tango, blue

  let size = (7, 6)
  let offset = (size.at(0) + 1, 0)
  let start = 0.001
  let end = 1
  let domain = (start, end)
  
  plot(
    size: size, x-tick-step: 0.5, y-tick-step: 0.2,
    x-min: start - 0.1,
    x-max: end + 0.1,
    y-min: - 0.1,
    x-label: [Wavenumber $k$ (rad/s)],
    y-label: [Energy $P(k) (m^2 s$)],
    plot-style: tango,  // <--------- is this correct?
    legend: "legend.inner-north-east",
    {
      add(domain: domain, line: "spline", label: [10km], t => jonswapEnergy(t, 10000, 10))
      add(domain: domain, line: "spline", label: [20km], t => jonswapEnergy(t, 20000, 10))
      add(domain: domain, line: "spline", label: [50km], t => jonswapEnergy(t, 50000, 10))
      add(domain: domain, line: "spline", label: [100km], t => jonswapEnergy(t, 100000, 10))
    }
  )})

I was wondering how to use a palette with a plot, I would like to change line colors. In the docs it says that the plot-style parameter of plot accepts a function and saw a discussion for bar charts that uses the parameter bar-style in a similar way

This is the result (it makes the plot all black):

This seems to be a solution, I was missing the stroke: true in the palette function:

plot-style: i => (fill: none, ..cetz.plot.default-plot-style(i), ..tango(i, stroke: true)),

Not really clear from the documentation/manual, I had to read the source code and #repr results in order to find this.
