/* PRISM authored-content rendering: headers, callouts, questions, and their
 * input controls (prism-*). Previously this CSS lived only inside
 * PrismRenderer::getStyles(), which is emitted in exactly one place (the
 * PRISM editor preview iframe). Every other consumer of PrismRenderer output
 * (decks, the teacher lesson view, the PRISM library view) rendered these
 * class names completely unstyled, so a short-answer textarea fell back to
 * the browser default cols=20/rows=3, about 180px wide.
 *
 * Loaded from app/views/partials/prism/assets.php, included from the same
 * layouts and standalone views as partials/math/assets.php, since anywhere
 * math can appear, a PRISM question can appear too.
 *
 * WCAG 2.1 AA: nothing below 0.75rem. See documents/WCAG-STYLE-GUIDE.md.
