   of only expanding the branch containing the current page (Furo's
   default). Furo implements collapsing purely in CSS: each branch with
   children gets a hidden ".toctree-checkbox" and its nested "<ul>" is
   "display: none" unless that checkbox is ":checked" (which Furo only
   does for the current page's ancestor branch -- see
   src/furo/assets/styles/components/_sidebar.sass and
   src/furo/navigation.py). Forcing the nested list to always display
   makes every top-level section's pages stay visible regardless of which
   page is currently open. */
