    💡 真实 URL 源默认通过 web-capture-api 网页提取服务抓取（可每源改获取方式与参数）；example.com 等占位地址走模拟数据。<br>
    ⏱ 采集周期：0=跟随所属机制全局值（普通源=设置页采集间隔，定制源=定制监控间隔），填分钟数则本源自定义。<br>
    🌐 获取方式：<b>自动</b>=优先 web-capture-api、失败回退直接抓取；<b>web-capture</b>=仅走网页提取服务；<b>直接抓取</b>=requests+正文清洗。设置页可改 web-capture-api 地址。<br>
    🎯 <b>定制监控</b>：与新闻监控独立，无权重，按「推送标准」由大模型判断是否推送，命中实时推送 + 单独汇总。
