Overview

Vendored Google Closure Library bootstrap module providing the core `goog` namespace and dependency management used by Selenium JavaScript atoms.

Description

goog (base.js) is a vendored copy of the Google Closure Library bootstrap file. It establishes the base `goog` namespace, sets up the global object reference, and provides the core dependency management system including `goog.provide`, `goog.require`, `goog.module`, and `goog.define`. In uncompiled mode it loads Closure's deps file for module resolution. Selenium uses this as the foundational layer of its JavaScript atom infrastructure for browser automation commands.

Usage

This module is consumed internally by Selenium's JavaScript atoms build system. It is not imported directly by end users.
