/* =====================================================================
 * 手机适配。全部在 max-width 媒体查询里，桌面端不受影响。
 *
 * 模拟编辑器在手机上不硬挤：main.js 给它们保留桌面版宽度，整体 transform 缩小到
 * 屏幕宽（body 上会挂 .fit-mode）。所以这里分三块：
 *   A. 页面级的排版，任何时候都生效；
 *   B. 编辑器内部的"挤一挤"规则，只在没有 JS 缩放（没有 .fit-mode）时兜底；
 *   C. 有 .fit-mode 时，把 styles.css / styles-2.css 里的窄屏规则拨回桌面值。
