/**
 * CSS dùng chung cho mọi tool — toàn bộ class có tiền tố "pth-" để không xung đột với theme

 * KHÔNG thêm CSS riêng cho 1 tool cụ thể vào file này — nếu 1 tool cần trình bày kết quả khác
 * biệt hẳn, ưu tiên dùng cấu trúc HTML/class đã có; chỉ thêm class mới khi thật sự cần và vẫn
 * giữ tiền tố "pth-".
