この拡張機能について
One button, one precise goal. Watch the hand circle a bell dial and strike when it crosses the golden window. Three clean strikes complete the round; three misses end it. The window and hand speed change gently across the three bells, with immediate feedback for every attempt. Start Again opens a fresh round. The popup stores a local count of completed rounds, runs offline, and needs no website access or account.
