/* Subsection headings inside a section, layered on top of
   css/section-headings.css: the projects index nests categories under a
   section, and the research index nests publication years.

   The labels share the left edge of the cards they introduce. The change of
   axis, not just of size, is what keeps them from reading as section headings
   in their own right.

   Card titles are also headings, but .project-card__name and
   .research-card-content carry classes and so win on specificity. */
