风格化粒子动画依赖外部 CDN 的 Three.js，全站同域脚本策略会阻止其加载，导致 THREE 未定义。现在使用同域 ES module，保留原 Three.js 0.160.0、动画参数及 MIT 许可。 扶苏在 2026-11-04 09:44 收到的 gpt-image-2.5 HTTP 524 响应是 Cloudflare HTML 页面，错误正文被直接保存和显示。现在将这类响应显示为结果未确认的超时提示；已有历史消息在渲染时同样归一化，不改动原始记录。524 不触发自动模型切换，避免原任务结果未确认时再次生成。普通 HTML 文档和代码示例保持原样。 验证：原生产 CSP 下的本地浏览器验证粒子有可见像素、连续帧变化、窗口缩放及无外部请求、无脚本错误；637 项辅助测试通过、1 项原有跳过，包含供应商 524 只提交一次、结果未确认、不自动切换及正常 503 行为。TypeScript、改动文件 lint、凭据、日志脱敏、环境、元数据、测试与制品检查通过。 已知问题：全量 lint 仍有 1004 项历史诊断。524 的根因是上游长请求超时，本次修复错误展示与未确认结果的处理，不承诺消除线路侧偶发超时。
