/* ============================================================================
   预约表单样式重构（2026-10-02）
   ----------------------------------------------------------------------------
   这次要解决三个真实问题：
     1. 【控件不一致 / 最严重】旧 CSS 只写了 .contact-fields input 一条规则，
        select 与 textarea 完全没被定义 —— 于是在深色弹窗里渲染成系统默认的
        「白底黑字」，与整站的深色主题彻底割裂。
     2. 【按钮藏起来】表单内容高 1076px、弹窗可视高只有 862px，提交按钮落在
        屏幕外，用户填完表单根本看不到按钮。
     3. 【只排单列】桌面端 600px 宽的弹窗里一列到底，竖着拉得很长，横向空间
        白白浪费。
   做法：三类控件统一规格 → 桌面两列网格 → 字段区滚动 + 底部操作区固定。
   改动只在样式层，name / id / class 契约全部保持不变。
