How can I update the figure counter ignoring the figures with `supplement: none`?

I didn’t dive deep into this, but since some direct changes are impossible, there is also an explicit counter update:

#import "@preview/subpar:0.2.2": grid as sgrid

#let trans-linear(caption: none, column: 60pt) = {
  sgrid(
    columns: (column,) * 3,
    caption: caption,
    figure(rect[left]),
    figure(rect[center]),
    figure(rect[right]),
  )
  if caption == none { counter(figure.where(kind: image)).update(n => n - 1) }
}

#trans-linear(caption: none)
#trans-linear(caption: "Homegeneity")

I just don’t know about the kind. If it’s just the standard image kind, then it’s all should be good, otherwise you might need some additional tweaking.
