//! **The files half of the records pane**: where the work lands, what the
//! worktree holds, and the bounded preview of one file in it.
//!
//! Split from [`super`] beside [`super::steps`] and for its reason (bl-d1ae):
//! the pane file is the pane, and this is one section of it with the two
//! sentences it paints computed beside the paint.
//!
//! **The worktree's absence and an empty listing are two claims**, and the
//! wire keeps them two on purpose — so this half paints two sentences where a
//! tidier one would have painted one.
