   Native `<details>`/`<summary>` accordion. No JS needed —
   browser handles open/close. Chevron is a CSS pseudo-element
   that rotates on `[open]`.

   The clickable summary area is the entire question row (its
   `cursor: pointer` covers the full padding) so editors don't
   need to worry about hit-target size.
