/* ══ 产品页页头：高度与字号统一向首页海报轮播区（.hero-slider）看齐 ══
   轮播区文字标尺：.h-kicker 11.5/3.5 · .h-copy h1 clamp(27,2.7vw,34)/w800/1.34
                 · .h-slogan 13/1.8 · .h-meta 12
   页头原标尺比之大一档半，故整体下调：
     眉标 12.5 → 11.5px（ls 4 → 3.5，同 .h-kicker）
     标题 clamp(30,4.2vw,48) → clamp(27,2.7vw,34)，w700 → w800，ls .5 → 1.5，lh 1.28 → 1.34（同 .h-copy h1）
     副文 16.5 → 13px（lh 1.8，同 .h-slogan）；上距 20 → 16
     数据行 27 → clamp(16,1.7vw,19)px；小字 13.5 → 11.5px
     数据行上距 46 → 28、内距 34 → 20、限宽 780 → 660（同 .h-meta 收紧口径）
   字号部分不加媒体查询，窄屏同样生效；高度部分须留在 min-width:901px 内，
   否则会因 id 优先级高于 ≤900px 的 `min-height:0` 而把手机页头撑高。
   作用域仅 3 个产品页 —— #page-home 首页、#page-contact 联系页不受影响。 */
