1//! The default screen, built from the view's public widgets only: a
2//! [`TranscriptPane`] over the shown agent, which takes what the other
3//! panels leave, the [`InlineStrip`] of a question asked beside the work,
4//! and the input, an [`Editor`] with the shown agent's [`StatusLine`] in
5//! its bottom row. An app
6//! that builds its own screen adds [`TuiViewPlugin`](crate::TuiViewPlugin)
7//! without this one and spawns its own, marking the transcript and the
8//! editor the keys go to [`MainPane`] and [`MainEditor`].
