/* Paid cloud: account, pricing, sign-in pages, nav pill and the paid parts of the tool.
   Loaded only when the paywall is on for the request (account.js adds it at run time; /account/ and /pricing/ link it),
   so public pages with PAYWALL=off are untouched. Mobile first: the base rules are the 390 px phone, min-width goes up.
   参考：refs/amie（窄版心、三层 6% 投影的白卡、12px 圆角按钮、灰色说明）、
         refs/aboard（浅灰白底、品牌淡色 --brand-soft、实心主按钮 + 淡色次按钮）。
   Colours come from style.css (--brand); inputs 16 px; primary buttons 48 px and full width on phones. */
