Stage 5 — Experiment on the Branch

Rewrite style.css with a dark theme while standing on the dark-theme branch. Commit. Watch main stay exactly the way it was.

What You'll Learn

How commits attach to the branch you are currently on
That main is untouched while you experiment on another branch
How to switch branches and see a completely different version of your files

Prerequisites

You finished Stage 4. git branch shows main and * dark-theme.

What Changes

style.css is rewritten with dark colors and teal accents.
One new commit is added — but only on the dark-theme branch. The main branch is untouched.

Outcome

On dark-theme: the page has a charcoal background, teal heading and button, and a dark scoreboard panel with a teal border.
On main: the page still has the light gray background from Stage 3. No changes.
git log --oneline on dark-theme shows four commits. On main, still three.
