You can simplify this by using numbering, counter, and spread operator:
#set heading(numbering: (..nums) => {
let chapter-count = counter("chapter counter")
if nums.pos().len() == 1 {
// Level 1: Roman numerals for Parts.
numbering("I", ..nums)
} else if nums.pos().len() == 2 {
// Level 2: Use the chapter state counter and increment it.
chapter-count.step()
str(chapter-count.get().first() + 1)
// or
// context numbering("1", ..chapter-count.get())
} else {
// Level 3+: Use the chapter number followed by the position within that chapter.
numbering("1.1", ..chapter-count.get(), ..nums.pos().slice(2))
}
})
