/* =====================================================================
   主题 t10 · 仪表盘数据型（dashboard）
   设计语言：顶部信息条 + 巨型 KPI 数字 + 数据表样式 + 常驻右侧信息板。
   与现有 t1-t8 显著差异：
   - 产品展示用 .db-prod-table 表格（行业 / 型号 / 价格 / 操作），打破卡片范式
   - 数字卖点用 .db-kpi-card 包裹的 KPI 模块
   - 侧栏用 .db-sidepanel 始终贴边展示
   - 整体观感像数据后台的「经营报告」
