/* ============================================================
   KaTeX integration.

   The formulas are pre-rendered at author time, so this file and
   the KaTeX stylesheet are all that is needed to display them —
   the page loads no maths JavaScript.

   KaTeX draws in currentColor throughout, so both themes work
   without overrides; what it does not do is stay inside a narrow
   column, hence the scroll containers below.
