当 Claude Code 通过 ANTHROPIC_BASE_URL 指向中转/代理端点时，会读取系统时区与中转域名，通过 Unicode 隐写术编码到 system prompt 中，用于判断用户是否来自中国地区。
本工具模拟其中部分检测逻辑（时区检测），并结合 5 项浏览器指纹，给出 0–100 的加权评分，帮助你了解自己的浏览器环境是否可能被判定为中国用户。
| 信号 | 权重 | 说明 |
|---|---|---|
| 系统时区 | 30 | Intl.DateTimeFormat 读取的 OS 时区 |
| 浏览器语言 | 24 | navigator.languages 首选语言 |
| 中文字体 | 20 | Canvas 2D 字体探测 |
| Intl 区域 | 10 | 日期/数字格式区域 |
| 时区偏移 | 8 | getTimezoneOffset |
| Emoji 风格 | 8 | 由 User-Agent 推断 |
总分 = Σ(命中权重 × 命中强度)，满分 100。
所有检测在本地浏览器内完成，不会上传任何数据。
