   2026-10-07 · 重点强化 + 手机端适配 v2
   ------------------------------------------------------------
   起因：卖家反馈「进站抓不住重点」+「手机端要自适应」。
   实测：横向溢出全站为 0（自适应本身没坏），真问题是
     ① 首页 8 个 h2 同权重并列 → 没有主次
     ② 手机端首页 12748px(≈15 屏)、首屏被文字塞满
     ③ 手机端「免费试用」被 .nav__cta 规则隐藏 → 转化入口消失
     ④ 手机端价格表 6 个产品各占一屏，无法对比
   对策：① 首页加「三步走」主线 + 二级节视觉降级
        ② 首屏瘦身、hcard 补回桌面主视觉（原来只有文字，右半边空着）
        ③ 手机端底部常驻 CTA 条（免费试用 + 加微信）
        ④ 手机端价格表改紧凑对比卡，一屏看完 6 个
