/* ─── AEO Answer Block (.hzo-answer) ────────────────────────────────────────
   The visible surface for W-004 (answer.php): ONE question as a real heading
   + a 40–60-word answer-first paragraph optimized for AI Overviews / featured
   snippets. Three display modes — inline (default, always-visible AEO shape),
   card (boxed), disclosure (native <details>). The FAQPage/QAPage JSON-LD is
   PHP-emitted and has no styling surface.

   Tokens only — no bare hex/px/ms, no z-index (this block never portals or
   stacks). schema="off" still renders the visible block; a schema-carrying
   block adds only an invisible <script>. */
