//! Minimal mouse-capture commands for the TUI.
//!
//! `crossterm::event::EnableMouseCapture` enables five DEC private modes at
//! once: ?1000h (basic), ?1002h (button-event motion), ?1003h (any-event
//! motion), ?1015h (urxvt) and ?1006h (SGR). The motion-tracking modes make
//! host terminal emulators refuse to honor their modifier-bypass for native
//! drag selection (Option/Shift+Drag on iTerm2/Terminal.app, Shift+Drag on
//! most Linux terminals), because even no-button mouse motion is reported to
//! the application as a captured event.
//!
//! These commands enable only ?1000h (button press/release, which includes
//! scroll-wheel events as buttons 4/5) and ?1006h (SGR coordinate format).
//! Scroll events still reach the app, but drag motion is not captured, so the
//! terminal emulator can perform native text selection when the user holds
//! the bypass modifier.
//!
//! On Windows the full crossterm commands are re-exported, since the
//! any-motion concern does not apply in the same way to Windows Terminal /
//! Conhost.
