 * base.css —— tdfront 全站样式基线（2026-08-29 起替代 Bootstrap 整包）
 *
 * 内容 = Bootstrap v4.6.2 (https://getbootstrap.com) 中被本站页面实际命中的 70 条规则，
 * 由 deploy/remove-bootstrap-20260829/extract.js 在 24 个渲染后页面上机器提取，保留原顺序与 @media 包裹；
 * 两处人工改动：small 字号钉回 4.0.0 的 80%（维持现状视觉）、删去 print 的 @page{size:a3}。
 * 与原整包(4.0.0) 逐像素验证一致（14 页 × 3 宽度 + focus/hover/分页态，差异像素 0）。
 * 原始版权：Copyright 2011-2022 The Bootstrap Authors / Twitter, Inc. — Licensed under MIT
 * (https://github.com/twbs/bootstrap/blob/v4.6.2/LICENSE)
 *
 * ⚠️ 这是唯一的全局基线：新页面若用到这里没有的 Bootstrap 类（.row/.col-*/.table 等）不会有样式，
 *    新样式一律写进 td.css，不要再引整包。
