Visual Testing & Accessibility — quiz

First time you run `expect(page).to_have_screenshot('home.png')` — what happens?

• It silently saves the baseline and passes
• Without `--update-snapshots`, the first run fails because no baseline exists yet — this is intentional, so you don't accidentally accept a wrong baseline. Run once with `--update-snapshots` (or the shorter `-u`) to capture the baseline; subsequent runs compare pixel-by-pixel against it
• It fails with a generic error and won't save anything
• Visual testing only works in headed mode
