Waking a Dead Service Worker with Web Push, from a Cloudflare Worker

A Chrome extension gained Web Push so teammates can be alerted even when its Manifest V3 service worker has gone idle and been terminated.

The client subscribes to push notifications and shows a clickable alert when a message arrives.

A Cloudflare Worker generates standards-based Web Push messages using Web Crypto, including VAPID signing and encryption, without Node libraries.

The approach demonstrates how push can wake an otherwise dead extension service worker only when needed.
