/* Q-Smoke web. Màu lấy từ app (lib/theme.ts): BG #0a0a0f, CARD #13131a, BORDER #222230, TEXT #e8e4dc,
   MUTED #6b6860, DIMMED #4a4a5a, INPUT_BG #0f0f18, INPUT_BORDER #2a2a3a, trạng thái #4ade80 / #facc15 / #f87171.
   Tiêu đề serif đậm như app (Georgia 900) → Noto Serif (có đủ dấu tiếng Việt). Chỉ có giao diện tối, như app.
   Trên web, chữ phụ dùng --soft sáng hơn MUTED của app để đủ tương phản khi đọc đoạn dài. */
