[dsk-dev-ai]

Description

Adds a clarification explaining the difference between Document.querySelector() and Element.querySelector().

Motivation

This distinction is a common source of confusion for developers. The documentation previously did not clearly explain the scope difference between these two methods. This update helps readers better understand how each method works in practice.

Additional details

No functional changes. This is a documentation improvement with a simple example to illustrate the difference.
