   SLai · 精修层 v6  「整洁 + 冲击力」
   -------------------------------------------------------------------------
   诊断（对照 900×700 实测截图）：
     1) 留白失控：hero 上下左右间距不一致，内容贴边
     2) 层次扁平：标题、正文、元信息几乎同样亮度，一眼看不到重点
     3) 装饰过多：网格 + 极光 + 噪点 + 光晕叠在窄屏上变成"糊"
     4) 节奏不齐：trust chips 换行后错位，spec 表格与左侧文字不对齐
     5) 首屏没有"焦点物"：右侧仪表盘被压缩到看不见

   修法（全部保留原配色：紫 #A855F7 / 青 #67E8F9 / 深紫黑底）：
     · 8pt 栅格：所有间距统一到 8 的倍数
     · 三级文字：标题 100% / 正文 72% / 元信息 46%，拉开层次
     · 收掉多余装饰：窄屏只留极光，关网格与噪点
     · 首屏改两栏固定比例，仪表盘最小 420px，不压缩
     · 每个板块加"视觉锚点"：数字 / 图标 / 细线，避免一片文字
