/* index.md's title heading is kept in the source (Sphinx needs a real
   section/title node for the page <title> and sidebar) but is visually
   hidden, since the banner image directly below it already serves as the
   page's visible heading. Scoped to that specific heading's auto-generated
   section id, not a reusable class, so it doesn't affect any other page —
   if the heading text in index.md changes, this id must be updated to
   match (Sphinx slugifies the heading text to produce it). */
