需求：后台新增设置，允许管理员上传自己的图标；上传后首页品牌图标与浏览器 标签页 favicon（以及「添加到手机主屏」图标）一起换成它。 要点： - 一张上传图服务端居中裁剪成正方形，生成 16/32/48/64/180/192/512 + maskable 192/512 整套尺寸，并手工拼装多帧 favicon.ico。 - 单一来源 site_icon_url() 统一取址；site_icon_head() 被首页/登录页/后台 三处共用；PWA manifest 改由 manifest.php 动态输出、maskable 也跟随 —— 三处防线共同杜绝「首页换了、标签页还是旧的」这类半生效。 - 目录可写则落静态文件（最快）；不可写的保守环境整套压进设置、由 site-icon.php 按需输出，功能不因权限限制整块不可用。 - 与「网站列表里每个网站自己的图标」是两个维度：目录与设置键都分开， 清理时互不误伤。 顺手修掉两个真问题： - login.php / admin/_auth.php 各留了一行写死的 favicon，与新的 site_icon_head() 并存 → head 里两条 rel="icon"，是「上传了却没换」的 温床。已删掉写死那两行。 - 自定义 favicon.ico 原先只塞 16+32 两帧，而内置是 16/32/48/64 四帧 —— 换图标反而退步。已补齐 icon-64 并统一为 4 帧。 - setting() 的请求内缓存导致「同请求写后再读」拿到旧值（真实坑）： settings_cache() 支持强制重载 + settings_reload()，写入后立即失效。 验证：单测 44/44（含只读目录动态回退）、HTTP 56/56、e2e 174/0、 反向验证 5 变体全部被抓住（含「写死残留」与「ico 只塞两帧」两个新哨兵）、 真机几何 360/390/768/1440 无溢出、线上直连桌面+移动端几何全绿、 线上诊断页走通「上传→前台全换→复原」。
