/* ── FAQ hub (/faq.html) ─────────────────────────────────────────────────
   Layered on css/site.css, which owns the accordion itself (.faq-item-
   accordion / .faq-question / .faq-answer, driven by js/page.js). This file
   adds the hub's own chrome: sticky category bar, filter + expand/collapse
   tools, match highlighting, permalinks, category tiles and the column
   alignment of each category's intro. The pre-2026-09 rules for a
   <details>-based FAQ that no page uses any more were removed. */
