 * Tệp này chạy ở CẢ HAI nơi: trang thật và khung xem trước trong trình dựng.
 * Nhờ vậy những gì người dựng thấy đúng là những gì khách nhìn.
 *
 * NGUYÊN TẮC: CHỈ ĐẶT NHỮNG GÌ BẮT BUỘC
 * -------------------------------------
 * Mỗi luật ở đây là một luật mà người dùng phải ghi đè nếu muốn khác đi. Đặt
 * càng nhiều thì bảng cài đặt càng khó thắng, và sẽ có cảnh "chỉnh mà không
 * thấy đổi gì". Vì vậy ở đây chỉ có:
 *   - khung xương (flex, grid, tỉ lệ khung hình),
 *   - giá trị mặc định trung tính (khoảng cách, cỡ chữ cơ bản),
 *   - và những thứ không đặt được từ bảng cài đặt (hiệu ứng, trạng thái mở/đóng).
 *
 * Toàn bộ dùng tiền tố `elb-` nên không đụng vào CSS sẵn có của website.
