/* ============================================================
 * 阶段8 美团严选（公域联盟）— 商品展示 + CPS跳转
 * 配套：portal-stage8.js（拉商品/跳转购买）
 * 版本：v=0904d5
 *
 * 设计原则（与 portal-stage4/stage7 一致 — 工具栏风格）：
 *   - 视觉退后（公域联盟非主项）
 *   - 浅灰底 + 细边框 + 小图标
 *   - 桌面 4 列 / 平板 2 列 / 手机 1 列
 *   - 微信 X5 兼容：触摸目标 ≥44px、最小字号 12px
