/* ================================================================== *
 * 移动端（768 及以下）
 * 上面各段已有的 640 / 420 / 720 断点继续生效，这里补 768 这一档：
 * 手机竖屏（375–430）大多同时命中 640 与 420 两档，本档负责
 *   · 工具页表单不再限宽 660、输入框满宽、按钮 44px 高
 *   · 工具箱首页在 768 就排两列（三列在手机上字太小）
 *   · 结果表的缩略图列收窄，表格允许横向滚动而不是撑破屏幕
 *   · 实时预览的按钮条在手机上整行排开
