   无滚屏全屏布局 / 动感主屏 / 五书签 / 五面板
   配色：鼠尾草绿 + 烫金  ·  气质：极简 · 书卷 · 克制
   ------------------------------------------------------------
   布局铁律（勿改，改则三柱/面板溢出复发）：
   1. .panel 绝对定位铺满，.panel-body 负责唯一滚动
   2. .pillars 用 flex + align-items:stretch 自然等高，禁止硬编码高度
   3. .pillar 禁止 overflow:hidden，禁止内部滚动
   4. 球体类名固定 .sphere-core，禁止复用通用类名
