/* 质安检测官网 · 视觉系统 v3 · 变体 C「权威机构感」定稿（2026-09-13）
   块面：藏青大面积（首页 hero、内页标题带）；纸色与白色区块交替；深藏青页脚。
   印章：品牌方印「质安检测」田字格，单层 inset，1px 格线；页脚反白版用白色内框。
   铭牌：证书信息按记录排版——纸色底、黄铜顶线、CMA/CNAS 方戳、等宽证号。
   徽标：全站证书徽标统一为铭牌上的细框方戳（1px 语义色框、无底色），双证用两枚并排。
   黄铜色只用在 2 处：证书铭牌顶线、资质页铭牌表顶线。其余组件不得再用黄铜。
   流程：细线六格（顶部规则线 + 格间 1px 竖线，无框无底），序号沿用藏青小方块。
   青绿只做交互色（链接 hover、焦点、当前筛选）。
   r1（2026-09-13 复审修复）：hero 铭牌右缘对齐版心（subgrid）；业务索引三张实景图恢复为全彩竖幅大图；
   六类卡恢复细线品类图标（右上角）；可点卡标题带淡底线；≥1000px 正文/表格/提示框统一 42em 栏宽，宽表 .wide 例外；
   科普页目录 ≥1100px 浮到右侧；移动端主按钮 ≥44px、顶栏保留美团预约。
   r2（2026-09-13 第二轮）：底部预约条只在 ≤700px 手机出现（平板走顶栏美团按钮）；手机 hero 收紧、铭牌 CMA 整卡进首屏、美团预约恢复实心；
   ≤1100px 出血图与铭牌共用右缘；h2 规线遇到自带顶线的组件（表格/流程/顶线卡/铭牌）时让位，不再双轨；
   标题带小标签分两类：证书戳带 CMA 红 / CNAS 蓝语义色细框，栏目名改无框短刻线；关于页六步与首页同一套细线六格；
   业务详情页标题带配图改全彩；两标准对照表窄屏走横滚；联系页两卡不再强制等高。 */
