Fast mode, and the prompter's curve on sent messages
Fast mode is selectable per session where the backend supports it, and a sent message now wears the same curve as the prompter it was typed into.
Fast mode reaches the model picker as a mode rather than as a separate entry in the catalogue, so choosing it does not mean re-choosing the model.
The visual half: a message you sent used to lose the shape of the surface you typed it in the moment it left. Sent messages now carry the prompter's superellipse, which is what makes a transcript read as a conversation with the composer rather than as a log beside it.
The same pass removed a set of dividers that were separating things already separated by their own surfaces.
