/* ARCADIA CRM — หน้าตาตามต้นแบบที่พี่เล็กอนุมัติ (design/crm-prototype.html)
   Layout: เต็มความกว้างจอทุกขนาด · จำนวนคอลัมน์ปรับเองด้วย grid auto-fill / flex-wrap (ไม่พึ่ง media query — Center-Safe Mobile)
   media query ใช้แค่สลับเมนู: จอ >= 900px เมนูอยู่แถบบน / จอเล็กเมนูอยู่แถบล่าง (ถ้า media query ไม่ทำงาน ก็ยังใช้แถบล่างได้ปกติ) */
