//! Structural pins for the Ctrl+C documentation drift (#1770, #1771).
//!
//! The real behavior lives in `src/tui/app/state.rs`: when the transcript is
//! scrolled up (`!auto_scroll`), the first Ctrl+C press snaps back to bottom
//! and clears the input — no quit, no quit hint. Both documented surfaces
//! (README shortcut table, `/help` dialog) described only clear-input/quit,
//! lying by omission. Source scans keep the docs welded to the behavior.
