/**
 * 首页样式 · 极简浅色（vben 统一风）
 * ============================================================================
 * 改版说明
 * ----------------------------------------------------------------------------
 * 旧版是「科技感暗场语言」：19 处渐变、扫描线、双色光晕、青紫配色。
 * 与用户中心 / 后台的 vben 极简浅色严重割裂，同一站点看起来像两个产品。
 *
 * 本版只保留真正有信息量的元素，砍掉纯装饰：
 *   · 背景：无网格、无扫描线、无光晕 —— 纯 #f7f9fc
 *   · 主按钮：实色（与 vben primary 一致），不用渐变
 *   · 标题：不再用渐变文字，改用字重与字号建立层级
 *   · 流水线示意：不再做成「仪表盘」，而是三行极简步骤
 *   · 卡片：白底 + 1px 边框 + 8px 圆角，无阴影堆叠
 *
 * 设计约束（与 vben 对齐）：
 *   圆角 8px / 卡片 12px   —— vben --radius
 *   主色 #536dfe           —— 与用户中心主色一致
 *   文字 #1f2329 / #6b7280 / #9ca3af
 *   边框 rgb(0 0 0 / 8%)
