How does Polylux slides work?

I has been inspecting the current package for creating slides, and I think I can understand the most of the logic of #pause in their source code. However, with the Polylux package, it seems like there are no hide functions working on the content after it.

#let pause = {
  // We need two separate `locate`s because `repetitions` needs to be updated
  // using the new value of `pause-counter`.
  context {
    if not handout-mode.get() {
      pause-counter.step()
    }
  }
  context {
    repetitions.update(rep => calc.max(rep, pause-counter.get().first() + 1))
  }
}```
and nor the parsing content that utilize the mark of pause... 
```typst 
#let polylux-slide(body) = {
  context {
    if logical-slide.get().first() > 0 {
      pagebreak(weak: true)
    }
  }
  logical-slide.step()
  subslide.update(1)
  repetitions.update(1)
  pause-counter.update(0)

  // Having this here is a bit unfortunate concerning separation of concerns
  // but I'm not comfortable with logic depending on pdfpc...
  let pdfpc-slide-markers(curr-subslide) = context [
    #metadata((t: "NewSlide")) <pdfpc>
    #metadata((t: "Idx", v: counter(page).get().first() - 1)) <pdfpc>
    #metadata((t: "Overlay", v: curr-subslide - 1)) <pdfpc>
    #metadata((t: "LogicalSlide", v: logical-slide.get().first())) <pdfpc>
  ]

  pdfpc-slide-markers(1)

  body

  subslide.step()
  set heading(outlined: false)

  context {
    let reps = repetitions.get().first()
    for curr-subslide in range(2, reps + 1) {
      pause-counter.update(0)
      pagebreak(weak: true)

      pdfpc-slide-markers(curr-subslide)

      body
      subslide.step()
    }
  }
}

How is that possible?

Hello!
Were you looking for this?

#let paused-content(body) = locate( loc => {
  let current-subslide = subslide.at(loc).first()
  let current-pause-counter = pause-counter.at(loc).first()


  if current-subslide > current-pause-counter {
    body
  } else {
    hide(body)
  }
})

I think the de facto standard for slides is touying at the moment (2024-12-09T23:00:00Z).
