/* Màu âm vị (từ) và vai ngữ pháp (câu) apptienganh, đi cùng visual-hierarchy.mjs.
   Bảng màu do chủ dự án chốt, KHÔNG đổi màu. Cách hiển thị chủ dự án duyệt 28/10/2026 (đề xuất 2):
   - Từ: chỉ có màu và khung trọng âm. Không vạch dưới, không gạch chấm, không cung nối.
   - Chữ không đọc thành tiếng (k của knife, b của lamb, e cuối của cake/have) đều màu xám #94a3b8.
   - Câu: gạch dưới chỉ ở đuôi ngữ pháp (chữ s, -ing, -ed). Không đánh dấu từ trọng tâm.
   Lý do sư phạm: mỗi kênh nhìn chỉ mang một nghĩa (nguyên tắc báo hiệu, dư thừa của Mayer); trẻ chưa học
   "magic e" không hiểu cung nối, và chữ e tô xanh dễ bị đọc thành âm "e".
   Không để CSS disabled/opacity của nút đè các màu này thành một màu. */
