Git zones

Git divides changes into three zones: working directory, staging area, and local repository.

• Working directory — real project files on disk. This is where you edit the code.
• Staging area (index) — a temporary area where changes are placed via git add.
• Repository (.git) — Git's internal database where commits, branches, and history are stored.

The sequence looks like this: changes → git add → staging → git commit → repository.
