/* ============================================================
   EQIO 简快测控 · 品牌主题 v5(新 VI 深工业绿)
   值源:eqio-vi/brand.tokens.json(品牌版本 1.2)。
   设计原则延续:高级感来自克制——白与墨绿黑承担大面积,
   品牌绿(#176B4A)只做点睛(细线/链接/主操作/选中提示);
   超大标题、编辑式排版、去卡片化、双倍留白。
   深色底上的交互强调使用亮绿 #69C69A。
   本文件在 style.css 之后加载,通过变量重映射 + 组件覆盖换肤。
