/* sma-v2.css
   Small companion stylesheet for modernized SMAdata content pages. Loaded
   alongside rtdc-v2.css (not instead of it) — this file only adds the
   components rtdc-v2.css doesn't already provide: prose subheadings, a
   data table, notice lists, prominent link buttons, code/pre blocks, a
   side-by-side code comparison table, and the SMAdata_FAQ table-of-contents
   and Q&A layout. Everything else (header, nav, .rtdc-page shell, .rtdc-card,
   footer, base typography) comes from rtdc-v2.css. */
