Review Summary

Your solution is approved because it fully meets the functional and visual requirements of the stopwatch task. The stopwatch is correctly centered on the page, has the specified circular size and dotted border, and uses clean BEM naming for the block, elements, and the stopwatch--speed-up modifier. Both the seconds and minutes hands match the required dimensions, colors, starting position at the top, and use only CSS animations, with the seconds hand running 60s linear and the minutes hand using 3600s steps(60) for a full rotation. The speed-up modifier correctly adjusts only the animation durations to 10 seconds and 10 minutes respectively, without breaking the base behavior. Your keyframes use from/to with a transform: rotate(...), which aligns with the checklist requirements. Overall, the implementation is clean, passes all stated requirements, and does not contain any critical or blocking issues. Great work solidifying CSS animation and BEM concepts in this solution.
