   - 主题变量着色，亮/暗主题均可读；自定义箭头取代各平台不一致的原生箭头
   - 补齐基础外观基线（边框/圆角/背景/字号/内边距/焦点态），使任何位置的
     孤立 select 都自动统一；.form-row / .grid / .power-rule / .tv2-props 等
     上下文规则优先级更高，仍可各自覆盖尺寸
   - !important 仅用于箭头相关属性：业务 CSS 常用 background 简写，
     会隐式把 background-image 重置为 none
   - 注意：Windows/Chromium 的展开弹层由系统绘制，下面 option 规则只是
     no-script 降级；正常展开层由 shared/select-ui.js + 第 15 节 .sel-pop 接管
