/* ============================================================
 * B 版 · 温暖插画 / 卡片流风格
 *
 * 设计语言（与 A 版刻意对立）：
 *   · 暖色系：陶土橘、奶油、深咖，大量渐变与柔光
 *   · 大圆角（18–28px）、多层阴影、玻璃拟态
 *   · 卡片堆叠、悬浮、渐变描边 —— 有体积感
 *   · 底部常驻 Tab 导航，图标 + 文字
 *   · 数字用圆润无衬线，标题带轻微喜剧感
 *
 * 目标观感：像一本身边的小册子 App，亲和、好读、有温度
 * ============================================================ */
