//! A tiny section heading for the commit screen.
//!
//! saudade's `Label` honors `layout()` but anchors its text at the slot's
//! top-left corner. `Heading` is a minimal left-aligned, *vertically-centered*
//! text widget that honors `layout()` and whose text can be updated (e.g. to
//! show a live file count).
