 * THÔNG BÁO TUYỂN SINH — Flatsome Raw HTML + CSS bổ sung
 * Scope: .fss-ts

 * Flatsome → Section → Advanced → Class:
 *   - Một section chứa toàn bộ nội dung: chỉ gõ `fss-ts`
 *   - Section / khối HTML *tiếp theo* (cùng trang, nối dưới): `fss-ts fss-ts--continue`
 *     (hoặc gõ nhầm `fss-ts--continu` — vẫn được hỗ trợ)
 *   Không bắt buộc gộp cả hai trên section đầu nếu chỉ cần một nền liền.
