Review Summary

Your solution is approved because it fully meets the functional and visual requirements of the stopwatch task. The .stopwatch block is correctly sized at 80vmin with a 1vmin dotted black border, and the center circle, minute hand, and second hand all use the specified colors, lengths, and widths. Both hands start from the top using transform-origin: bottom center, and their animations rely only on CSS @keyframes with from/to and transform: rotate(...), which satisfies [CHECKLIST ITEM #1]. The seconds hand completes a full rotation in 60s with a linear animation, and the minutes hand uses steps(60, ...) over 3600s to achieve discrete minute jumps, matching the task requirements. Your stopwatch--speed-up BEM modifier correctly updates the custom properties to 10s and 600s durations and is applied in the HTML, so the accelerated mode behaves as expected. BEM naming is consistent, the stopwatch is centered via the flexbox .container, and there are no functional or checklist-breaking issues. Nice work implementing the details accurately and keeping the structure clean.
