1//! Bottom status-line span assembly.
2//!
3//! [`build_status_lines`] collects keybinding hints, session label,
4//! auto-apply badge, bus status, latency, token usage, and status
5//! text into one or more [`Line`]s for the status bar. When the
6//! terminal is too narrow to show everything on one row, the
7//! content is stacked across three lines.
