/* ==================================================================
   唯美视觉增强层（2026-09-21）
   调性：Soft Pastel Blur Marketing —— 白底 + 粉/蓝/黄大柔光晕染，
   “像水彩还没干”的温润感；卡片圆角放大、蓝色调柔和阴影。
   安全红线（改这里必须守住，任何一条破了都会伤功能）：
     ① 装饰层一律 position:fixed + z-index:-1 + pointer-events:none，
        盖不住内容、也吃不到任何点击；
     ② 主内容卡片保持不透明白底，玻璃态只给导航（backdrop-filter），
        绝不给内容卡片加模糊（会伤可读性）；
     ③ 入场动画是渐进增强：默认可见，只有 JS 跑起来才加隐藏类，
        JS 挂了内容一字不少照常显示；
     ④ 全部尊重 prefers-reduced-motion。
     ⑤ 柔光用多段 radial-gradient 自带柔和衰减，不用 filter:blur()，
        手机端才不会卡（这是刻意的性能取舍）。
