/* Doki – vỏ app (đợt G, A1; làm lại theo bản demo ở đợt U3). CHỈ có tác dụng khi <html> có class "app-mode" (appmode.js) – trang web thường không đổi gì.
   Gồm: thanh app ở trên (logo + chuông / nhạc / giỏ), thanh 5 tab ở dưới, trang chủ app (lời chào, thẻ ví, dịch vụ nhanh, quà tặng theo dịp),
   các trang đè Dịch Vụ / Khóa Học / Tài Khoản, và cách xếp lại đầu trang /shop trong app.
   Chữ theo thang type.css: ≥13px, 14–16px đậm ≤700, ≥17px ≤800 (nhãn thanh dưới dùng 14px thay vì 12px của demo để dễ đọc). Mục chạm ≥44px (vùng bấm nới bằng ::before). Chừa env(safe-area-inset-*). */
