   Thu phí sát hạch — trang tra cứu "/" và quản trị "/tp-admin" (mockup thu phí v3, 25/09/2026).
   Cùng bộ token với phần mềm quản lý thí sinh (assets/qlts-giao-dien.css): xanh navy, vạch vàng,

   Chỉ đổi giao diện — quy trình, nội dung, tên trường form giữ nguyên bản production.

   /tp-admin/login luôn sáng + Turnstile; Portal học viên đã gỡ (bỏ CSS của Portal).
