/* ==========================================================================
   套餐参数 · 公共样式
   --------------------------------------------------------------------------
   对应模板片段 template/package-plan.html（{{template "dnsPackagePlan" . }}），
   DNS_Product.html 与 DNS_table.html 两个页面共用这一份 HTML + 这一份 CSS，
   改一处两页同步，不会再出现"两个页面的套餐表不一样"的情况。

   来源：从 DNS_Product.css 里按"套餐参数区块 + 它要用到的公共件"整段搬过来：
     1) .dp-btn 系列——套餐表下方的行动按钮要用（ --primary-blue 由 global.css 提供）
     2) .main-center / .dp-section-title——套餐区块的版心与章节标题
     3) .taocan-* / .dp-table-*——套餐区块自身，含窄屏横向滚动与首列吸附
