/* ============================================================
 * 今心为岸 · 简约清新版 v3.0
 * 设计师：设计师（SheJiShi）· 100005038
 * 日期：2026-09-12  v3.0（重设计系统）
 *
 * 设计哲学：
 * 「一盏渡父母 · 留白即美 · 简约即大美」
 *
 * v3.0 重设计：
 * · 从"古风水墨"→"现代简约清新"
 * · 底色：暖白（#FAF9F6）+ 浅米（#F5F2EC）
 * · 主色：朱砂（#C8483E）+ 古金（#C9A961）—— 降饱和度
 * · 灰阶：暖灰 #2C2C2C / #6B6B6B / #9B9B9B / #D4D4D4 / #ECECEC
 * · 字体：保留宋体气质（标题），正文用现代无衬线
 * · 装饰：极简——只有 logo/朱印点缀
 * · 圆角：8px 统一圆角
 * · 阴影：极淡（最多 4% 透明度）
 * · 间距：更大留白（呼吸感）
 * ============================================================ */
