//! Regression test: ensure that `StatusIndicatorWidget` sanitises ANSI escape
//! sequences so that no raw `\x1b` bytes are written into the backing
//! buffer.  Rendering logic is tricky to unit‑test end‑to‑end, therefore we
//! verify the *public* contract of `ansi_escape_line()` which the widget now
//! relies on.
