Other: Web Push API (service worker notifications)

An interface allowing web applications to receive messages pushed from a server even when the browser is closed or inactive.

The Web Push API leverages Service Workers to handle incoming payloads via the PushEvent, enabling re-engagement through system-level notifications. By utilizing a Push Service (like Firebase Cloud Messaging or Apple Push Notification service) and VAPID keys for authentication, developers deliver real-time updates without keeping a tab open. This standard bypasses the need for constant polling, reducing battery drain and data usage for users on Chrome, Firefox, and Safari.
