/* ============================================================================
 * Steam 入库 栏目页（**本机预览，未上线**）—— 与 qdm-steam-20261006.js 配套
 *
 * 路由：/?category=steam-ruku  （和「联机修复工具 / 平台修复工具 / 游戏工具」同一形式）
 * 结构参考同类工具落地页：主视觉 → 为什么选我们 → 三步上手 → 套餐 → 常见问题 → 底部 CTA
 * ⚠️ 文案与参数全部是**本站自己的初稿**，没有照抄参考站；带【待定】的地方等你给准确值。
 *
 * 做法：进入这个路由时把本站「分类页」的框架部分收起来（站点 hero、RESOURCE CATEGORY、
 *       排序栏、空状态），在 .page-shell 里插入一整页落地内容。
