/* ═══════════════════════════════════════════════════════════════
 *  RIP RUST Store — 商店专有样式
 *  Version: 1.3.1 | Author: Joker
 * ═══════════════════════════════════════════════════════════════
 *
 *  外壳（Reset、设计令牌、背景动画、导航、Hero、页脚、公共按钮
 *  与滚动行为）全部由主站的 core.css / elements.css / theme-*.css
 *  提供。本文件只补充"电商所需的组件"：筛选器、商品卡、购物车侧
 *  边栏、商品详情弹窗、赠礼弹窗、Steam 登录条、通知条、分页器、
 *  自定义响应式微调。
 *
 *  颜色一律通过 var(--*) 引用主站令牌；本文件不得写入品牌硬编码色，
 *  因为一旦主站换主题（a-street / b-blaze / c-venom），本页要自动跟随。
 *  半透明色以 rgba(var(--*-rgb), 透明度) 形式表达，避免绑死具体色号。
 *
 *  版本说明：任何一次样式变更都必须同步 bump wrangler.toml 的
 *  ASSET_VERSION，否则边缘/浏览器会长期持旧文件。
