Visual Proof
Screenshots are the only claim about a page's appearance that cannot be hallucinated. Capture before you change anything, and after.
If you cannot capture — no server, no Chromium, no network to the deployed URL — say so and stop making visual claims. Describing a page you never rendered is the single most common way UI work goes wrong undetected.

Six shots per state. Not one, not a single desktop hero crop.
| Width | Stands for |
|---|---|
| 375 | phone — where layouts actually break |
| 768 | tablet / the awkward middle breakpoint |
| 1440 | desktop |
