   苏州密泰新材料 · 官网设计系统 v4 ·「工业长卷」
   ──────────────────────────────────────────────────────────────────────
   【v4 要解决的真问题】v3 把颜色收敛干净了，但版式仍是"一版块一版块"的
   模板结构：十几个全幅色带上下堆叠、每块 96px 留白、白灰交替、
   每块一个居中大标题 —— 页面像十几张卡片拼起来，气韵断在每道色带边界上。

   【v4 的四个结构性动作】
     1) 去色带、留画布：取消白/灰交替底色，全站一张连续冷白画布，
        板块之间只用 1px 细线分隔。视觉连续，页面才"长"得起来。
     2) 章节号：每个板块标题上方一个大号描边序号 01 02 03…，
        把散落板块串成一条可读长卷。顺序本身成为设计元素 —— 工厂该有的工序感。
     3) 单一高潮：全站只保留一处深色满幅（工厂与产线），其余全部浅色。
        强调靠"唯一性"，不靠到处铺色。
     4) 紧凑 + 锐角：区块节奏 96px → 64px；卡片圆角 12px → 3px。
        锐角是工业品的语言，圆角是消费品的语言。

   【色源】仍全部取自 logo，不引入第五种色相
     · 墨蓝 #0B1B2E 骨架 / 品牌蓝 #0076FF 唯一强调
     · 天青 #22C1FF 冷光点缀 / 环保绿 #4DBA46 只做语义点
