/* ==========================================================================
   app.css — giao diện app Kho vật tư kỹ thuật WinCommerce (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 / hộp thoại / đăng nhập. App có hai màn (Tổng quan, Danh sách kho) và
   một màn chi tiết mở từ danh sách, nên không dựng thanh bên: hai tab nằm trên
   topbar (quy tắc #14), giống app khảo sát nhận diện.
   Thay cho design-system.css + ui-polish.css + inventory-specific.css (bản 1).

   tailwind.css (Tailwind v3, dựng lúc deploy) nạp TRƯỚC file này, nên cùng độ
   đặc hiệu thì quy tắc ở đây thắng. Giao diện mới không dựa vào utility của
   Tailwind; nó chỉ còn giữ phần reset (preflight).
