   app.css — giao diện app Hiệu suất nhân sự kỹ thuật (2026-09-23)
   --------------------------------------------------------------------------
   Theo quy tắc chung WCM (DESIGN_SYSTEM.md bản 2, app gốc là app cửa hàng):
   cùng token, cùng kiểu topbar / đầu trang / bộ lọc / menu / thẻ số / thẻ /
   bảng / đăng nhập. App này chỉ có một màn nên không có thanh bên; logo nằm
   ở topbar.
   Thay cho design-system.css + ui-polish.css + dashboard.css (bản 1, đã bỏ).
   File nạp SAU tailwind.css: các class wcm-* thắng utility cùng độ đặc hiệu.
