/* v9.0.2-1 */
/* ============================================================
   PHOTO UPLOAD v8.4.3-9 (NEW - CLEAN CSS)
   - Viết mới hoàn toàn, KHÔNG tham khảo CSS cũ
   - Bám theo template trong photo-upload-v8.4.3-4-1.js
   - Theme chính: teal -> sky, màu theo đúng chức năng
   - Fix vấn đề cuộn/che trường: dialog flex, body scroll, footer cố định trong dialog,
     có padding-bottom + safe-area để không che input cuối.
