Apple Watch 起床闹钟

An alarm that checks you actually stood up, built for Apple Watch with an iOS companion. I wrote a PRD, architecture notes and a risk document first, then used a real device to test the risky parts (AlarmKit behaviour and wake detection) before building more.

Honest status: a proof of concept from a few days of work (6 commits), not a product.

中文：一个带 iOS 配套应用的 Apple Watch 起床闹钟，用来确认你真的起床了。先写了 PRD、架构和风险文档，再在真机上验证最有风险的部分（AlarmKit 行为和起床检测）。目前只是几天的概念验证（6 次提交），不是成品。
