/* ===== 首页 hero 价格表（2026-10-21 v8）：深底表条统一背景，彻底去掉黑马纹 =====
   病因（v7 失败原因）：首页表格里 th 行和 td 行同属一个 tbody，tr:nth-child 计数把表头算成了第 1 行，
   于是 even/odd 正好错位：被设成“透明”的那一半落到 td 上，被通用规则 tr:nth-child(even) td{background:#fbfcfe}
   涂成白底，再配浅色字就看不见。修法：不再依赖奇偶，所有数据行给同一个深色底（仅靠边框分隔），
   并用 !important 压过 gpu.css 前面的通用规则。作用域仅 body .hero table.price，不影响其它页面。 */
