// wxTimer Tests - Timer functionality for KiCad animations, auto-save, periodic updates
// Uses element registry for semantic element identification.
//
// Determinism: no waitForTimeout. Readiness via waitForWxApp; each button click's effect
// is the console event it emits, so we poll for that event (deterministic) instead of
// sleeping. The timer *tick* is a genuine scheduled event — the app logs each tick, so we
// poll for the tick log rather than guessing a duration. Mid-run "ticking"/"running"
// screenshots (which asserted nothing and whose pixels are timing-dependent) are dropped;
// the static loaded/started/stopped/reset states use stableShot.
