/* ===== 2026-10-30 案例页正文不再被右下固定联系条压住（.float-cta） =====
   量测事实（本地静态服务器实测，阈值取自真实 rect 而非估算）：
     · .float-cta：fixed / right 22 / width 234 → 左边界 = 100vw − 256；>900px 才显示。
     · .case4.case4-wide 两列断点原本是 981px，列宽恒定 `380px 1fr`。
       视口 1000→1239 时正文列只有 570→770px，而让位需求恒定 ~208px
       （正文右边界 = 100vw − 56，与视口无关）→ 让位后仅剩 217px ≈ 12 字/行，不可读。
     · 因此分两段处理：
       ① 901–1239：把案例改成**竖排**（图在上、正文在下满宽），正文可回到 580–840px；
       ② 全部 901–1640：正文右侧按公式让位
          need = (100vw−56) − (100vw−256−8) = 208 → 取 210；

   右边界 = 600 + 50vw。两者不重叠要求视口 ≥ 1712px，而实测 1024–1599 区间正文被压：
   tech-manual 203px、service-centrifugal 160px、pricing 130px、brand-york 116px、index 84px。
   做法：901–1599 区间折叠为 56px 圆形按钮（仍可直接拨号），hover / 键盘聚焦时展开成完整卡片。
     断点取 1599 的实测依据：1440 时首页正文仍被压 90px、1500 压 48px、1600 才归零；
     1439 折叠时 1440–1599 又恢复完整卡片 → 遮挡回来。所以折到 1599，1600 起才用完整卡片。
     · 折叠态只留 .fc-tel 的电话图标 → 点击即拨号，转化入口不丢
     · 展开态沿用桌面版原样式，没有任何「还原」规则，靠 :not(:hover) 反向写，不会漏属性
     · 卡片 right 固定、从底部向上长，展开时不会溢出视口

   ② 折叠后主 CTA 只剩 56px 圆钮，而「回到顶部」仍是 158px 蓝底胶囊，视觉权重反超主入口。
