background
Write the background here in plain markdown. It fills the circle and scrolls on its own.
As you scroll, the picture beside the circle changes at the percentages set in
images: above — this first one holds until you are 45% down.
Keep writing. The second picture takes over here, and the third near the end.
Add or remove images freely; the list is read top to bottom and the last one
whose at you have passed is the one showing.
Nothing is required except at: 0 on the first, so the space is never empty
when someone arrives.
favourites
Favourites. Same arrangement as the background pane — markdown in the circle, pictures tied to how far down you have read.
A pane needs no images at all. Leave images: off entirely and the space
beside the circle simply stays empty for that pane.
media
Media. One picture, pinned at 0, so it stays put no matter how far the circle scrolls.
gallery
Anything written here sits above the list.
