   of stretching to the bottom of the screen -- but a passage item needs the
   opposite: .eng-col-body's internal scroll only works if something in this
   chain has a *definite* height (a percentage height resolves to auto
   against an auto-height ancestor, per spec), so #col-passage being present
   restores the old fixed-height/flex:1 behavior; only WITHOUT a passage does
   the card fall back to auto/hug-content. Do not replace the height branch
   with `max-height` on .eng-item-card -- that was tried and silently broke
   the passage's internal scroll (the whole page scrolled instead). */
