How to increase the spacing between the number and the title of a heading?

This is what I came up with to get the links in the outline back:

#show outline.entry: it => {
  if it.element.func() == heading {
    // don't interfere with figure outlines (optional if you don't have one)
    let head = it.element // just to make our code shorter
    let number = if head.numbering != none {
      numbering(head.numbering, ..counter(heading).at(head.location()))
    }
    let fill = box(
      width: 1fr,
      it.fill,
    ) // ensure the fill doesn't occupy the full page width, just the available space (1fr)
    let toc-entry = box(
      //stroke: 1pt + red, //used for debugging
      link(head.location(), box(number + h(0.75em, weak: true) + head.body + fill + it.page)),
    )
    if head.level == 1 {
      strong(toc-entry)
    } else {
      toc-entry
    }
    v(-0.4em, weak: true)
  } else {
    it // use default style for figure outlines
  }
}

#outline(indent: 1.65em)
#pagebreak()

#set page(numbering: "1")
#counter(page).update(1)

#set heading(numbering: "1.1 ")

= First Headline 1
== First Headline 2
== Second Headline 2
#lorem(800)
= Second Headline 1
= Third Headline 1
#heading(numbering: none)[Literature]

What I couldn’t solve:

  • If you need indents for everything below level 1 you get line breaks, messing up the spacing, because the indent “overfills” due to the 1fr fill. I guess it would be possible to leave the indent and add a own spacing instead, substracting this spacing from the 1fr, but then the code would bloat even further and another if/loop for subsequent levels would be necessary. Update: I tried that but subsctracting from fractions is not possible or at least would involve further measuring steps. Maybe there is a compact/elegant solution I’m just not seeing? I also tried pad() for the indents, but that leads to the same problem, just that the line breaks is below instead of above.

  • The spacing needs the weird v(-0.4em, weak: true), which I suppose should not be necessary if done right – I think my code introduces some space where it should not?

Here is an editable link to see the example.

Would be really great if someone more experienced could take a look. :pray:
