Can the horizontal banner reel cascade like the main reels when a symbol was part of a win?

Yes -- the banner is a plain ReelSet, so it uses the same cascade API as the main board. Build it with .orientation('horizontal') plus .tumble({ fall, dropIn }), then await reelSet.refill({ winners, grid }) with the winning Cells ({ reel, cell }) and the next ColumnTarget[], or await reelSet.runCascade({ detectWinners, nextGrid }) for the whole destroy-refill-check loop. Progress is observable through cascade:fall:*, cascade:dropIn:* and cascade:chain:end.
