/**
 * TinyMCE accordion (collapse / expand) blocks inside topic content.
 *
 * The official self-hosted accordion plugin writes:
 *
 *   <details class="mce-accordion">
 *     <summary>Section title</summary>
 *     <p>Hidden body…</p>
 *   </details>
 *
 * Inside the editor the summary also has .mce-accordion-summary and the
 * body is wrapped in .mce-accordion-body (TinyMCE unwraps that wrapper
 * on save). These rules cover both shapes so writing matches reading.
 *
 * Loaded on the reader page, the admin content view, and the TinyMCE
 * editing iframes (through content_css). No JavaScript — <details> is
 * native HTML5.
