/* ============================================================================
   Chợ An Tâm — giao diện sàn mua bán C2C
   ----------------------------------------------------------------------------
   Nguyên tắc (xem thêm README):
     · Phần công khai nhìn như một chợ điện tử thật: học Shopee/Lazada cho trang
       chủ, Chợ Tốt cho tin đăng, eBay cho quản lý giao dịch. KHÔNG làm kiểu ngân
       hàng/fintech dù hệ thống có ký quỹ.
     · Màu chủ đạo cam cho hành động mua bán; xanh "tin cậy" CHỈ dùng cho những gì
       thuộc về ký quỹ, xác thực và an toàn — để người xem nhận ra ngay đâu là phần
       bảo vệ tiền.
     · Một file duy nhất, không import, không font web: CSP của dự án chỉ cho tải
       tài nguyên từ chính máy chủ.
