/* ═══════════════════════════════════════════════════════════════════════════
   dialogue-practice.css — luyện hội thoại (public/learn/shadowing/hoi-thoai.php) + Ôn câu sai (hoi-thoai-on-tap.php).

   Giao diện "Phòng thu" (25/09/2026 — cùng hướng A chủ site chọn cho trang Shadowing video). Dải teal đậm của App học v3
   làm sân khấu: cảnh đang nói (người nói + nghĩa câu + chuyển câu + trình phát) bên trái, danh sách câu bên phải. Thẻ luyện
   trắng chồng lên mép dải (Nghe & gõ / Điền từ / Shadowing). Dưới cùng: tổng kết + bảng hội thoại.

   Nạp SAU learn-shell.css + learn-ui.css (trang gọi lv_dlg_assets() trước) và roadmap-practice.css (khung .rp2-* dùng chung
   với trang luyện tập lộ trình — KHÔNG sửa file đó, bản sao byte-identical với TTKK). Mọi phần riêng đặt ở đây, phạm vi .dps.
   Chỉ token, không hex; dải luôn tối, thẻ tự lật theo token (sẵn-sàng-tối).
