/* Collapsed by default; opens via .is-open (toggled by faq.js).
   Uses the CSS grid-template-rows trick so it animates smoothly to/from
   "auto" height without any JS height-measuring.
   IMPORTANT: minmax(0, 0fr) / minmax(0, 1fr) — NOT bare 0fr / 1fr.
   A bare 0fr track still has an implicit "auto" minimum, so on narrow
   (mobile) widths — where wrapped answer text is intrinsically taller —
   the row silently grows to fit that content instead of collapsing to
   true zero, letting a sliver of the answer peek out even while closed.
   Wrapping in minmax(0, ...) forces a real zero-height minimum so the
   row (and therefore overflow: hidden below) actually clips it. */
