/* ==========================================================================
   宁波森燚机械制造有限公司 官网样式
   --------------------------------------------------------------------------
   设计原则：
   1. 浅色底 + 白色卡片承载内容，用「层次」替代「大面积色块」；
   2. 深蓝作为主色但只做重点点缀，工业橙只用于按钮与关键数字；
   3. 正文 15~17px、行高 1.75，移动端不缩字号、不横向溢出；
   4. 所有尺寸用 clamp()，一套代码自适应手机到宽屏。

   说明：这是「提高门槛」而不是「绝对防住」——访客仍能看到内容，
        也仍能通过截图、拍照等方式留存，真正的防盗要靠水印与法律手段。
        表单输入框保留正常选择与复制，避免用户填手机号时无法粘贴。
   注意：只作用于前台样式表，后台管理页不受影响（后台未引入本文件）。
