/* 微视印 · 模板类工具共享样式
 *
 * 十个模板页（名片 / 课程表 / 菜单 / 证书 / 邀请函 / 房源卡 / 价签 / 工牌 /
 * 优惠券 / 座位表）骨架一致，样式集中在这里，页面 HTML 不再各写一份。
 *
 * 两条硬约定（来自 theme.css 的既有结论，别在这里破坏）：
 *   1. **不反转预览区**。.stage 在深色下依然是深色底，但画布本身画的是白底卡片，
 *      导出的像素与浅色模式完全一致 —— 用户不会误以为导出结果会变暗。
 *   2. 深色只压暗"外壳"（.app / .editor / 表单控件），这里新加的组件
 *      （.rows-* / .notice / .image-thumb）必须自带深色分支，否则会深底深字。
