/* detail.css định nghĩa .empty-state dùng chung toàn site là position:absolute;inset:0 (để phủ
   kín ô chart rỗng ở trang chi tiết cổ phiếu). Component ở đây chỉ cần 1 khối nội tuyến bình
   thường trong panel — nếu không huỷ position/inset, bất cứ lúc nào 1 trong các ô rỗng này hiện
   ra (style.display='block' set từ JS) nó sẽ phủ TOÀN BỘ TRANG (kể cả header nav ở trên cùng) và
   chặn hết click, vì .bigflow-panel .empty-state chỉ override đè được đúng những thuộc tính khai
   ở đây — position/inset không khai lại thì vẫn kế thừa nguyên từ rule gốc dù rule này specific hơn. */
