/* ============================================================
   Leonis AI 中转站 · 全站推广位样式（P1 / P2 / P3 / P4 / P5）
   ------------------------------------------------------------
   设计原则：
   1. 圆角 / 阴影 / 字体 / 文字色一律复用本站 styles.css 的设计令牌
      （--radius-* / --shadow-* / --ink-* / --line / --surface），
      不引入外来风格，也不改动任何既有选择器。
   2. 本站主色是蓝色系（--brand-*），Leonis 用金色渐变作为「合作推荐」
      的独立识别色，与站内自营业务（代充值 / 成品账号）在视觉上分区，
      读者一眼能看出这是并列的第三条路，而不是站内商品。
   3. 站点固定浅色（:root 声明了 color-scheme: light，全站无深色变体），
      因此这里刻意不写 prefers-color-scheme: dark 覆盖——否则系统深色下
      只有推广位变深，会与页面其余部分割裂。
   4. 在 styles.css 之后加载，同特异性下可安全覆盖。
