   Trà Sữa Idle — giao diện

   Mobile-first, tông ấm kiểu quán trà. Mọi hình vẽ đều là SVG
   nhúng sẵn (không icon font, không emoji của hệ điều hành) nên
   hiển thị giống nhau trên mọi máy và chơi offline được.

   Quy ước màu của "ô icon": mỗi mục game được gán một hue (xem
   js/look.js), CSS tự suy ra nền/viền/màu nét từ hue đó. Nhờ vậy
   danh sách nhiều màu mà không phải khai báo từng mã màu.
