/**
 * Core Details block (core/details) — AU-style FAQ accordion.
 * Visually identical to the Yoast FAQ skin (assets/css/faq-yoast.css), but
 * driven entirely by CSS: <details> keeps its own open state, so there is no
 * JS and the block degrades to a plain, fully readable Q&A list.
 *
 * Numbering comes from a CSS counter, so questions must NOT be numbered by
 * hand in the editor.
