   กฎ: ไม่มีค่าสีฝังในไฟล์ ทุกสีอ้าง --cs-* จากไฟล์แบรนด์
   ลำดับการโหลด
     หลังบ้าน:  brands/<brand>.css → ke-core.css → ke-admin.css → theme.js
                (หรือใช้ theme.css ซึ่งคือ core + admin รวมไฟล์เดียว)
     เว็บไซต์:  brands/<brand>.css → ke-core.css → ke-site.css → theme.js → ke-site.js

   ไฟล์ theme.css ถูกสร้างจาก build.sh อย่าแก้ theme.css ตรง ๆ ให้แก้ไฟล์ ke-*.css
