/* ==========================================================================
   TEMPLATE 2 — Demo tĩnh (ui-template-demo-4) — bản "Mềm" (lần 2, 2026-10-02)
   --------------------------------------------------------------------------
   - Bố cục: sidebar trái nổi (bo tròn) + topbar + nội dung — giữ khung đã chốt.
   - Diện mạo: mềm, bo tròn, thân thiện — nút/ô nhập/tab dạng viên thuốc, thẻ bo 24px,
     bóng đổ nhẹ pha sắc độ của màu chủ đạo, font Nunito (đầu chữ tròn, hỗ trợ tiếng Việt).
   - Trung tính: nền/viền/chữ là thang xám PHA SẮC ĐỘ (--primary-h) của màu admin chọn
     (độ bão hoà rất thấp) nên đổi màu chủ đạo thì cả giao diện ngả theo nhẹ nhàng.
     Không có màu thương hiệu cố định. Màu trạng thái (xanh lá/vàng/đỏ/xanh trời) cố định.
   - Class mới đặt tiền tố `t2-`. Class "hợp đồng" (phụ lục A FEAT-23) giữ
     đúng tên để JS/view hiện có dùng lại được.
   - Mỗi khối "SECTION" tương ứng 1 partial SCSS khi port sang
     resources/sass/template2/_*.scss.
