   SLai · 精修层 v7  「密度 + 冲击」
   -------------------------------------------------------------------------
   对照 v6 截图（1440×1500）的三个问题：
     1) 标题对比太弱：渐变从 100% 白起步，实际渲染成灰紫，不够"亮"
     2) 首屏右半空太多：仪表盘下方一大片空，缺视觉重量
     3) 规格表 dt/dd 拉到两端，中间一条长空白，读起来断
   修法：
     · 标题改成"纯白主体 + 紫色描边光"，只在第二行做渐变
     · 右侧加"实时指标卡"，填满纵向空间
     · 规格表改成三列（标签 / 值 / 备注），紧凑对齐
     · 全文加"数据密度"：小字标签 + 数字，让页面有信息量感
