//! **The notice bar**: it stands where content would have been and says
//! whose it is, it wraps so its remedy reaches the glass, it wears its
//! state's ink, and it can be put down.
//!
//! Split from [`super`] at the line cap on the seam that file's own doc
//! draws: the layout is one subject and the bar that stands over it is
//! another.
