On a phone, several of our tool pages opened with a long intro and made you scroll to find the tool. The wall framing takeoff, the changepoint detector, the e-invoice preflight and the tennis robot shot planner now show a start button under the headline, and a second button that loads a worked example where the tool has one.
We checked at 390 px wide: every start button sits on the first screen, nothing scrolls sideways, and the example buttons work. We did not measure traffic or rankings. The change adds no new requests.
