/* Read-more / collapsible block — shared by villa-overview, accommodation-
   overview, and any future clamped prose (single source of truth; was duplicated
   per section). A `.ibv-readmore__content--clamp` element collapses to a fixed
   height with a teaser fade; `.is-open` (toggled by readmore.js) slides it to its
   natural height. `.ibv-readmore__toggle` is the trigger button.

   `interpolate-size: allow-keywords` lets `max-height` interpolate to/from the
   `max-content` keyword, so the block animates to whatever height the prose needs
   without measuring it in JS. Where unsupported the toggle simply snaps —
   progressive enhancement. */
