   ฟอนต์เก็บในระบบเอง (app/fonts/ — CSP font-src 'self') · ไม่มี inline style (CSP style-src 'self')
   หลัก: ป้ายสถานะต้องดูต่างจากปุ่ม (GOV.UK task list) · ตัวอักษรบนจอขั้นต่ำ 14px · ทุกปุ่ม/ลิงก์มี hover + focus
   ข้อความ/ข้อเสนอของ AI = โทนฟ้า + เส้นประ (ยังไม่ใช่ค่าที่อนุมัติ) · ไม่ใช้ม่วงไล่เฉด/อีโมจิ */
