ldtray 0.1.1

Cross-platform tray icons with zero compile-time linkage to platform GUI libraries — every toolkit is loaded at runtime via libloading, so headless daemons degrade gracefully instead of failing to link.

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