🎯 Use case
This file lives under “ink/”, which covers Ink terminal UI (layouts, TTY IO, keyboard, renderer components). On the API surface it exposes EventEmitter — mainly types, interfaces, or factory objects. Dependencies touch Node events. It composes internal code from event (relative imports). What the file header says: Similar to node's builtin EventEmitter, but is also aware of our `Event` class, and so `emit` respects `stopImmediatePropagation()`.
Generated from folder role, exports, dependency roots, and inline comments — not hand-reviewed for every path.
