/**
 * FAQ — PDF p.25.
 *
 * Light/cream page (unlike Partner/Careers). Left category rail controls
 * which category's questions show on the right; right side is a single-open
 * accordion. Category switching and the accordion are both plain DOM
 * show/hide — no page reload, no library — see assets/js/faq.js.
 *
 * RTL: logical properties + DOM-order layout — the category rail and the
 * plus/minus glyphs both need to read correctly mirrored; see assets/js/faq.js
 * and MISSING-ASSETS.md for how this was verified.
