QuickVocabCapture - Từ điển Tiếng Anh (IELTS/CEFR) & Tiếng Pháp (DELF/DALF) - Giao diện MochiMochi Chuẩn
Tính năng nổi bật:
1. Giao diện chuẩn MochiMochi theo đúng mẫu thiết kế:
   - Thanh Header với Logo MochiMochi, nút Nghe 🎧, Sổ từ đã lưu 📓, nút chuyển ngôn ngữ En - Vi ▾ / Fr - Vi ▾, Avatar Mochi, Ghim ⚙️
   - Ô tìm kiếm bo tròn viền vàng cam kèm vạch ngăn cách và kính lúp 🔍
   - Thanh Tab loại từ (Noun / Verb / Adjective ▾ | CEFR / DELF Context | Definition | Word Forms)
   - Tiêu đề từ vựng chữ lớn màu xanh đậm (#1E3A8A) + từ loại in nghiêng + nút [⊕ Lưu từ]
   - Dòng phát âm EN / FR 🔊 /ipa/
   - Danh sách các phiên bản nghĩa (1., 2., 3....) kèm huy hiệu CEFR (A1..C2),
     nút [⊕ Lưu từ] riêng cho từng nghĩa, và câu ví dụ + dịch tiếng Việt in nghiêng bên dưới.
2. Hai bộ cơ sở dữ liệu từ điển độc lập:
   - Tiếng Anh (En - Vi): E:\\tools\\english_dictionary.db -> lưu vào deck "hoc_lom" & danh_sach_tu_en.txt -> đồng bộ Hugging Face hung9066/mochi-english-anki-data
   - Tiếng Pháp (Fr - Vi): E:\\tools\\french_dictionary.db -> lưu vào deck "french2" & danh_sach_tu.txt -> đồng bộ Hugging Face hung9066/mochi-french-anki-data
3. Tự động bắt từ khi BÔI ĐEN + NHẤN PHÍM CTRL 2 LẦN LIÊN TIẾP (Double-Ctrl) hoặc nhập trực tiếp vào ô tra cứu.
