1//! Minimal end-to-end example.
2//!
3//! Shows a red tray icon with a small menu, prints every event, pops a
4//! notification when "Say hi" is clicked, and exits on "Quit". If no tray is
5//! available (headless server, missing libraries) it prints why and exits 0 —
6//! demonstrating the graceful-degradation contract.
