   HOW IT WORKS

   Collapsed cards have a FIXED footer height, so a title
   that wraps to two lines does not make one card taller
   than its neighbours. Titles clamp to two lines.

   The open card sizes itself to its content via
   grid-template-rows 0fr -> 1fr, so whatever the editor
   writes, the card fits it. No max-height, no scrollbars.

   The JS measures the tallest open card once and reserves
   that space on the row, so the section never resizes when
   you move between cards.
