/* ============================================================
 * RoyalCMS 国际化主题覆盖样式（深蓝商务克制风）
 * 设计参考：pophen / chinayongfa 国际制造业官网
 *
 * 设计原则：
 *   1. 单一深蓝主色 + 大面积留白，告别多彩渐变
 *   2. 衬线标题(Playfair/serif) + 无衬线正文(Inter)
 *   3. 克制阴影、小圆角、细分割线
 *   4. 内容居中收窄，呼吸感更强
 *
 * 本文件覆盖在 royalcms.css / royalcms.index.css 之后加载
 * 通过更高优先级或 !important 调整，不破坏原文件
 * ============================================================ */
