//! **What a ROW says**: its rollups, the pin order, the row this seat cannot
//! address, the classification it wears, and the click that aims the window.
//!
//! Split from [`sections`] at the line cap on the seam the pane itself has: a
//! section is one channel — its header, its address, and what it has instead of
//! walls — and a row is one workspace on it.
