/* ==========================================================================
   Login screen
   - Màu nền/màu chữ của cột login, input, nút... do app.themes.css quyết định
     theo từng theme (dùng !important). File này chỉ lo bố cục, kích thước,
     bo góc, khoảng cách, trạng thái tương tác.
   - Những chỗ cần ghi đè màu của theme thì dùng selector có #id hoặc
     độ ưu tiên cao hơn kèm !important.
