Users expect to press the Escape key to close modals, dropdowns, popovers, and toasts. Manually adding and removing keydown listeners everywhere leads to memory leaks and conflicts.
A single, reusable Escape key listener that attaches to document, triggers a callback, and
provides a simple cleanup function. SSR‑safe (no‑op on server).
