/* Google SERP Title & Snippet Previewer — content styles.
   Prefix: --sp-  /  .sp-

   Reference point: a literal search-result-shaped preview card is the
   result — not a metric row or table, since the whole point is "does
   this look right when someone actually sees it". Third writing-cluster
   tool this loop; distinct from the other two (no textarea-as-hero, no
   ranked table) — three separate input fields feeding one mockup card.

   THIS FILE STYLES THE CONTENT AREA ONLY. Chrome is owned by chrome.css. */
