What is Zephyr Events and why use it?

Tiny TypeScript event emitter. Race-condition safe — handlers won't skip during mid-emit unsubs. Beats EventEmitter3, Node's EE, mitt.

Is Zephyr Events faster than other emitters?

Yes, up to 82% in fast mode. Safe mode close enough for mortals. Zero deps, tree-shakeable.

Fully. Strict signatures. Define event types, get autocomplete and errors. No more `any` nightmares. (Word count: 942)

Event emitters are everywhere in JS. But most secretly skip handlers if one unsubscribes mid-emit. Zephyr Events? It doesn't play those games.
