Git Branch Isolation Tutorial: Why Uncommitted Files Follow You, Stash vs Commit, and .gitignore

A real-world, complete DevOps Git challenge walkthrough on setting up production workspaces, isolating feature code, and configuring ignore rules. If you have ever wondered why changes you made on one branch suddenly show up on another branch when running git checkout, how to prevent unfinished edits from leaking across branches, or why your commit failed with "error: pathspec did not match any file(s)", this video breaks down the full workflow step by step.
