   首页板块节奏校准 —— 逐项对照 rodbolpack.com（1440 宽实测）

   之前各块的 padding、标题条高度、卡片尺寸都是按「看起来差不多」估的，
   结果整页 8558px 的原站被做成 7261px，差了 1297px，滚动节奏完全不是一回事。
   这一段把每块的实测值写死，作用域限定在 .home-page，不影响内页。

   原站标题条（.title_bar）的真实构造：
     h2.title 高 44px（字号 44 / 行高 1）+ p.desc（padding-top 16 / 行高 17.6）
     = 77.6px，而且**没有 margin-bottom** —— 标题和内容的间距由各内容块
     自己的 padding 提供（product 53、else 48、application 64 …）。
   本站原来是 36px 标题 + 14px 副标 + 44px 下边距 = 126px，每块虚高 48px。
