   Version History & Changes sidebar.

   Standing beside the reading column on wide screens, and rendered as a top
   card on narrow screens. Uses `.card` (primitives.css) for its resting,
   in-flow surface -- unlike the popovers above it, which float. The section
   page's "Document Info" tab strips that card back off: it's a pane of its
   own there already, not something sitting loose atop other content. ===== */
