/* Same visual treatment as .content-card, but WITHOUT height:100% — used for
   several cards stacked vertically in one column (e.g. the programmatic pages'
   explainer sections). height:100% is safe for .content-card's original use
   (single card, or side-by-side grid columns) but creates a circular auto-height
   layout bug in Chromium when multiple 100%-height blocks are stacked inside a
   Bootstrap .row (a flex container) — each card ends up stretched to a huge,
   wrong height and overflows past its section. */
