A chat message bubble whose hidden/visible state is a pure function of the timeline. The renderer is a pure function of a MessageBubbleStyle (opacity, translateY, scale); useMessageBubbleTransition eases the rise-in enter. The incoming/outgoing variant resolves bubble color and alignment from the theme, and an optional reaction badge pops in on its own channel.
