update
Applies updateData as a shallow JSON-patch merge onto this event's current event — the mechanism behind UpdateEvents, the event-level equivalent of dev.catbit.mosaic.client.ui.sdui.foundation.tiles.holder.tile.TileHolder.update. Unlike the tile version, there's no special-cased nested field (no style equivalent) — every top-level key in updateData simply overwrites the matching key on the encoded event object, and the merged JSON is decoded back into a fresh T via the framework's dev.catbit.mosaic.core.serialization.MosaicSerializer.
Receiver
UpdateScope, which carries the dev.catbit.mosaic.core.serialization.MosaicSerializer this merge needs.
Parameters
updateData
the patch to merge onto this event's current fields.
