/* =========================================================
   绵阳师范学院美术系06级4班 · 20周年聚会 H5
   全局样式：复古怀旧 · 暖色调 · 移动端优先
   ========================================================= */

/* 默认配色「岁月清新」：面向 35 岁左右参会同学，跳出复古厚重的棕褐色调，
   改用清爽的薄荷青 + 珊瑚橙 + 靛紫，明快通透又不失活力，看起来更年轻。
   变量名保留旧命名（--c-brown / --c-gold 等）以兼容全站已有样式引用，
   实际含义已调整为：--c-brown-deep=标题主色，--c-brown=次强调色，
   --c-gold=主强调色（暖色点缀），--c-gold-light=浅色点缀底色。 */

/* 页面本质是手机端H5，在电脑等宽屏浏览器打开时，把整站限制在手机宽度内居中显示，
   避免顶部横幅铺满整个宽屏而中间卡片却居中，出现"错位"的观感。
   手机端屏幕本身小于此宽度，不受影响。
   注意：这里不能给 body 加 transform，否则会让 body 变成内部 position:fixed 元素
   （底部导航/提示条/弹窗）的定位基准，导致它们不再固定在"屏幕"底部，而是固定在
   "整页内容"的底部——页面一旦变长（如行程页很长），底部导航就会被顶到屏幕外，
   要滚动到页面最底部才能看到。所以固定元素改为各自用 max-width + 居中的方式
   限制在手机宽度内（见 .sfxy-nav 等），position: fixed 始终相对于真实视口。 */
