/**
 * ASAIGC 主页模块样式（v2 · 品牌化重构）
 *
 * 全部基于 pc/css/ui.css :root 的 5551 设计令牌
 * 命名空间：.lsah-* (LightSNS ASAIGC Home)
 *
 * 三风格容器：
 *   .ls-asaigc-style-waterfall  方案 A 瀑布流
 *   .ls-asaigc-style-workspace  方案 B 工作台优先
 *   .ls-asaigc-style-curated    方案 C 策展分块
 *
 * 品牌动机：
 *   - 主色单蓝 var(--ls-primary)
 *   - 火花 motif（RemixIcon ri-sparkling-2-* + .lsah-spark 动效）
 *   - 边框/阴影/圆角全部走 token
 *   - hover 行为统一：translateY(-2px) + shadow-md
