   CSP 安全的动态尺寸（2026-10-08）

   站点的 CSP 是 style-src 'self'，内联 style 属性会被浏览器拦掉：
     Refused to apply inline style ... violates style-src 'self'
   所以 element.style.width = '40%' 这类写法一律不生效。实测影响：
     - 首页上传进度条（#progressBar）从来没有显示过进度
     - 后台访客记录的柱状图 / 趋势图柱子宽度为 0，完全看不见

   解法：把百分比量化成 5% 一档，用 data-w / data-h 属性选择器表达，
   由 CSS 决定尺寸 —— 既不用放宽 CSP，也不影响可读性。
   JS 侧统一用 pctClass() 取档（见 public/js/admin.js 与 main.js）。
