The situation

You're deep in a feature branch with a half-broken build. Production page is on fire and the fix belongs on main.

`git worktree add` gives you a second checkout in a sibling directory — it needs a real second working directory, which this browser engine has not got. The portable fallback is stash → switch → fix → switch back → pop.

What you will practice

This scenario walks through 4 steps, in order:

1. 01Park the half-finished work, untracked files included
2. 02Switch to main to do the hotfix
3. 03Go back to the feature branch
4. 04Restore the parked work

Key takeaway

Stash-and-switch is the fallback every Git has. When you can use a worktree, prefer it: your half-broken build stays on disk untouched instead of being parked in a stash.
