Review Summary
I am requesting changes because some core visual and animation requirements of the stopwatch are not yet met and will likely cause tests to fail. The seconds hand currently uses the named color green and steps(60, end) timing; it must use the exact hex color #2c8000 and a smooth linear animation over 60s, e.g. animation: move 60s linear infinite;, so the motion is even without jumps. The minutes hand is missing its required animation entirely; it should rotate in 60 discrete steps over 60 minutes using something like animation: move 3600s steps(60, end) infinite; on .stopwatch__minute, and then the modifier .stopwatch--speed-up .stopwatch__minute can correctly override animation-duration to 600s. Both hand colors must use the specified hex values: change the minutes hand from blue to #0700ff and the seconds hand from green to #2c8000 to match the spec exactly. Once you add the minute animation, adjust the .stopwatch--speed-up rules so they effectively speed up both hands (10s for seconds, 600s for minutes) and everything else in your HTML and layout can remain as is. Overall the structure and sizing look good; fixing these color and animation details will bring your solution fully in line with the task requirements.

The seconds hand color uses the named color green, but the requirement states: "seconds hand should have a length of 38vmin and 1.5vmin width with green (#2c8000) color" — use the exact hex #2c8000 to meet the spec.

The animation on the seconds hand uses steps(60, end). The requirement says: "For the seconds hand use animation with even speed, without acceleration and deceleration. It should take the 60s for the seconds hand to make a full circle." Use a smooth timing function (e.g. linear) so the seconds hand rotates evenly over 60s, e.g. animation: move 60s linear infinite;.

The minutes hand currently has no animation defined. The spec requires: "For minutes hand use steps animation with 60 steps. It should take the 60min for the minutes hand to make a full circle." Add an animation to .stopwatch__minute like animation: move 3600s steps(60, end) infinite; (60 minutes = 3600s).

The minutes hand color uses the named color blue, but the requirement states: "minutes hand should have a length of 20vmin and 3vmin width with blue (#0700ff) color" — use the exact hex #0700ff for the minutes hand.

The .stopwatch--speed-up .stopwatch__minute rule sets animation-duration: 600s, but because .stopwatch__minute has no animation defined, changing the duration has no effect. Define the minute animation (see previous comment) so the speed-up modifier can override it to 600s (10 minutes).

Review Summary
I am requesting changes because one core visual requirement is not met, and this will cause the automated tests to fail. In src/styles/index.scss, the minutes hand selector .stopwatch__minute currently uses background-color: blue;, but the specification requires the minutes hand color to be exactly #0700ff. This is a critical blocker since the tests compare the exact color value and will treat the named color blue as incorrect. To fix this, update the .stopwatch__minute rule (look around the line where you set its size 20vmin by 3vmin) so that the property reads background-color: #0700ff;. Everything else about the stopwatch — structure, sizing, animations, and the stopwatch--speed-up modifier — appears to follow the requirements well, so once this color is corrected your solution should satisfy the task fully. Keep up the good work; this is a small but important detail to get your implementation over the finish line.

This violates the requirement: "minutes hand should have a length of 20vmin and 3vmin width with blue (#0700ff) color" — .stopwatch__minute uses background-color: blue; currently. Change it to background-color: #0700ff; so the minutes hand matches the spec exactly.

Review Summary
I am approving your solution because the stopwatch itself is implemented very well and matches the visual and animation requirements: the hands, center circle, sizes, colors, and timing behaviors (including the stopwatch--speed-up modifier) all look correct and work as intended. You did a strong job using CSS-only animations with the correct durations (60s for seconds, 3600s for minutes, and the sped‑up 10s/600s versions) and keeping the layout clean and centered.
There is one non-code issue to improve for future tasks: your Pull Request description is missing the required copied Checklist from the task description, where you should mark items as done (for example, using - [x] for completed points) [CHECKLIST ITEM #1]. This matters because it helps reviewers quickly verify that you’ve read and addressed each requirement, even when your code already passes them. To fix this next time, copy the checklist text into the PR description, tick off the items you completed, and add any short notes about testing or edge cases. Overall, this is an educational override to help you move forward while learning, and your implementation shows good attention to detail—keep up this level of quality and just remember to complete the process steps like the checklist in future PRs.
