Review Summary

Your solution is approved because it fully implements the required stopwatch functionality and visual design using only CSS animations. The stopwatch is correctly centered, sized to 80vmin with a 1vmin dotted round border, and both hands have the exact specified lengths, widths, colors, and start from the top using transform-origin: bottom center. The seconds hand rotates smoothly with a 60-second linear animation, while the minutes hand uses steps(60) over 3600 seconds, satisfying the timing and animation behavior requirements, including [CHECKLIST ITEM #1] and [CHECKLIST ITEM #2]. The stopwatch--speed-up BEM modifier is correctly implemented so that the seconds hand completes a rotation in 10 seconds and the minutes hand in 10 minutes, and the base stopwatch still works correctly when the modifier is removed. BEM naming is consistent, and there are no critical issues that break functionality or violate core requirements.

One process-related improvement: make sure in future PRs you copy the provided checklist into the description and mark completed items with - [x] so mentors can easily verify self-check, especially for [CHECKLIST ITEM #3] and [CHECKLIST ITEM #4]. Overall, this is a solid, standards-compliant implementation—well done.
