Sizing the grid to what each page happened to hold made the prose jump sideways every time a reader clicked from a page with headings to one without. The text should sit where it sat: the contents track is now always reserved, and an empty one costs nothing but space it was going to occupy anyway.

The left rail still follows :has — a doc page has no siblings to list, and reserving a gutter for nothing is a different mistake. closed check-in: 6d2a12980e user: dmestas tags: doc-reserve
