//! Standalone smoke for the libei input path on platform-linux.
//!
//! Drives `wayland::libei::move_absolute` + `click` and prints what happens.
//! Stress-tests the portal RemoteDesktop handshake plus the reis-based EIS
//! handshake on a real GNOME / KDE-Wayland host.
//!
//! Usage:
//!   CUA_DRIVER_RS_ENABLE_WAYLAND=1 \
//!   WAYLAND_DISPLAY=wayland-0 \
//!   cargo run --example libei_input --release
