- 匿名评论：comments.is_anonymous 列；对外昵称/头像/网址/徽标/等级/IP归属全部脱敏， 真实身份留 users 表（回复通知照发、autofill 不受污染）；邮件昵称也用「匿名」防泄露 - 表情包最近使用：面板顶部「最近」栏，localStorage 记录 8 个，零侵入复用 Artalk 插入逻辑 - 匿名开关插在 textarea 与底栏之间独立一行，不挤移动端底栏 - 自动填充：提示改 focusin 触发（原 input+sessionStorage 一次性门导致永不触发）； 已填昵称/网址时不覆盖并弹提示 - 邮件模板 UI 回退原版深色气泡设计，保留表情内联尺寸/主题文案等逻辑修复 - 返回顶部：rAF 自绘改 CSS scroll-behavior（滚动期临时挂类），修移动端掉帧
