/* Form đặt lịch hẹn — booking-schedule 2.1.0
 * Màu đi qua biến: --bk-main (màu chính), --bk-dark (thanh tóm tắt, chữ đậm), --bk-soft (nền ô).
 * Element "Form đặt lịch hẹn" ghi ba biến này lên wrapper từ option; không có thì theo màu chủ đề.
 * Mặc định khai ở :root — element ghi biến lên WRAPPER (tổ tiên gần hơn) nên đè được; khai trên
 * .booking-widget (con của wrapper) thì sẽ che mất option. */
