matrix-spec/layouts/partials/sidebar-tree.html

{{/*

  A version of the sidebar-tree.html partial in Docsy, with a few small
  modifications:

  * include `div#toc` for the ToC
  * start the sidebar at the root (homepage) since for us that is the Matrix
  overview page
  * omit module pages, which we don't want to be directly accessible
  (we only use them as raw material for the client-server spec)

*/}}
