"""Playwright RPA：从 SmartCampus HR 平台抓合同表 + 续聘材料包。

设计要点（v1.1.6，按 skill-template examples/real_browser_rpa 设计模式）：
- 使用 launch_persistent_context 复用浏览器登录态，避免密码硬编码
- 首次使用需用户手工登录一次（CLI 默认 --headless false 便于交互）
- 后续使用无头模式（profile 已存 cookie）
- **登录策略**：自动 fill demo/123456（sandbox 已知凭据） + 失败时 fallback 手工登录等待（轮询 180s）
- 抓表格：DOM eval_on_selector_all → JSON
- 抓材料：点 "续聘材料包" 按钮 → 抓卡片 inner_text

依赖为可选：playwright 未安装时 import 抛错，上层 CLI 捕获并降级报错。

导航流程（v1.1.1 强化版 — 强制 goto）：
1. goto 根域
2. 根域 login（如仍显示表单）→ 等跳到 /home 或 /select
3. 强制 goto sandbox SPA login URL
4. SPA login：自动 fill demo/123456，失败 fallback 手工等待（HUMAN_WAIT_TIMEOUT=180s）
5. 强制 goto SPA_HOME
6. click 侧边栏 hr/contracts
7. 等 table tbody tr（最长 ~40s）
