   AI 补给站 · 站点设计系统（默认主题：晨露翡翠清爽系）
   风格基调（2026-10-29 更新，杰哥定调）：**清透为主**——页面底色趋近白，绿色只作极轻渐变
            暗示；再叠一层几乎看不见的细纹（纸感），避免大面积平色显得单薄发闷；
            卡片/侧栏保持纯白 + 细线描边 + 极轻软阴影，靠明度差分而不是色块分层；
            chip 与 tab 一律描边式，实心色块仅保留主 CTA 按钮一处。

     - 细纹：内嵌 SVG 噪声（opacity 已烘进图形，约 3%），提供纸感、抗色带；
     - 三处 radial 光晕：薄荷绿在顶部、青绿在右下、琥珀在左下，都控制在 5% 上下。
