 ### DOCUMENT Token in Service
 
-Angular, being a platform-agnostic framework, is designed to support not only browser-based applications but also other environments like server-side rendering (SSR) through Angular Universal.

To address this, Angular provides a DOCUMENT token that can be used to inject the document object into Angular entities like components and services.
