 Progress 默认渲染为 `role="progressbar"`，并根据 `percent` 同步 `aria-valuemin`、`aria-valuemax`、`aria-valuenow` 和 `aria-valuetext`。当页面中有多个进度条时，建议通过 `aria-label` 或 `aria-labelledby` 提供可区分名称。
 
+`format` 会自定义可见进度文本；当 `format` 返回字符串或数字时，该内容也会作为默认 `aria-valuetext`。如果格式化结果是复杂节点，或需要让屏幕阅读器读取更完整的上下文，请显式传入 `aria-valuetext`。
