//! Named MSFS key events.
//!
//! The MSFS gauge API identifies key events by the numeric `KEY_*` constants
//! from `MSFS/Legacy/gauges.h` (lifted into [`crate::sys`] by bindgen). MSFS
//! WASM has no runtime name→id lookup, so this module exposes the subset the
//! avionics gauges need as [`EventId`] constants, plus `trigger_key` helpers
//! over [`super::trigger1`] / [`super::trigger0`].
