 * research-prose.css — styles the HTML produced by static/research-markdown.js.

 * The markdown engine emits SEMANTIC class names (ins-*) instead of Tailwind

 * accent — matching the original Research design — wired onto the Compass
 * design tokens (var(--c-*)) where it keeps us consistent with the rest of the
 * product. Rendered HTML is injected into <div class="research-prose">.
