Also I was expecting evaluation gauge to load from server analysis without running engine locally, but not sure if that is WIA or a bug.

Seems to be more than just the broadcast page - just saw this on https://lichess.org/broadcast/prague-chess-festival-2024--challengers/round-6/fTnA0Pwc/Q7r9LRuY too, but haven't seen this on the analysis board.
