{#-
  The stock partial draws nothing unless a page sits two sections deep, and even
  then it stops at the page's parent. On this site that left most pages with a
  single crumb repeating the section name already lit in the tab bar above it,
  and told you nothing about where in the section you had landed.

  Draw the whole path instead: every ancestor section, then the page itself,
  each labelled the way the left sidebar labels it, so the trail reads as the
  route you would have clicked to get here.

  A section hub page is the exception. It opens its section and carries its
  section's name, so its trail would be one crumb saying the title printed
  directly below it and linking to the page you are already on. Those pages, and
  the few that are built outside the nav, keep the row and drop the crumbs: the
  row's fixed height is what holds every page title at the same height.
