/* ============================================================
   FAQ PAGE — page-specific chrome only.
   Ported verbatim from `FAQ.html`'s own <style> block
   (couple-website-markup repo) — everything below is built from the
   global tokens in colors_and_type.css; only layout/structure unique to
   this page lives here. The shared `.faq-rail*` sticky-category-nav
   classes live in styles.css (moved there at Mobile Review S3) and are
   already part of Batch 0's verbatim port.

   NO-JS ACCORDION NOTE (Batch 1, 03_PAGE_DATA_CONTRACTS.md §1.3): the
   reference's accordion is React state (`isOpen`/`onToggle`); this port
   uses native `<details class="faq-item">` instead, so open/close works
   with zero JS. `[open]` replaces the reference's `.is-open` class below
   — same rules, same declarations. The "Expand/Collapse all" control and
   the answer-reveal slide-in keyframe are JS-only conveniences with no
   native equivalent, so both are dropped (native `<details>` still fully
   works without them; deferred interactive behavior, Batch 0 nav/footer
   precedent).
