+## Implementation Details
+- PostgreSQL + tokio-postgres + deadpool 连接池
+- argon2 密码哈希
+- UUID v4 session token + 30天过期
+- Dioxus 0.7.9 SSR Fullstack + `#[server]` 函数
+- Tailwind CSS CDN + darkMode class 主题切换
+- 首个注册用户自动 admin，后续注册关闭
+- wasm32 和 server 双目标编译
+
+## Verification Results
+- cargo check (server) ✅
+- cargo check (wasm32) ✅
+- cargo clippy ✅ (warnings only)
+- API tests: register ✅, login ✅, get_current_user ✅, re-register blocked ✅, wrong password ✅
