/* ============================================================
   KCK.CASA — Contact page (2026-09-02)

   目标：把页上两张表单（01 通用询盘 / 02 产品询价）统一成同一套视觉与交互语言，
   并整体提升到 "Refined European Industrial" 的设计水位。

   约束（改动前已确认，勿破坏）：
     - 表单 id / 字段 name 不能动 —— main.js 与本页 AJAX 依赖它们
     - input 与其 .form-error 必须同父级 —— JS 用 el.parentNode.querySelector('.form-error')
     - honeypot(website) 与 form_started 隐藏字段必须存在

   页面头图（.kck-page-hero）在共享层 kck-design.css。
