首页底部那张「站点统计」卡片下线，完整数据移到公开只读页 /stats： 今日实时数、概览六格、近 30 天折线与 12 个月柱状、三个占比环、 7×24 时段热力图、提问字数与回答耗时分布。 - 聚合在 internal/db/analytics.go（SUM(CASE WHEN)，方言差异收敛在 analyticsDialectFor） - 结果按自然日缓存，跨日重算一次后全站共用；重算失败降级返回上一份快照 - 图表零前端依赖：服务端算坐标的 SVG + CSS grid，禁用 JS 页面仍完整 - 环比取「上月 vs 上上月」：本月未过完，否则每月 1 号会得出 -95% - 入口只在页脚「社区规则」与「找站长」之间；route.Home 不再计算统计 - 补 questions(created_at) 索引；启动后异步预热当天快照 - 测试：analytics 连真库验证软删除不计入、分桶下标、DOW 对齐
