   ทิศทาง: ขายของ + ไฮเทค แต่ยังน่าเชื่อถือพอที่โรงพยาบาลรัฐจะเซ็นสัญญาด้วย
     · องค์ประกอบที่คนจะจำได้คือ "แผงข้อมูลปล่องสด" ที่หน้าแรก
       เพราะไม่มีโรงกำจัดขยะเจ้าไหนกล้าเปิดข้อมูลปล่องให้ดู — นั่นคือของขายจริง
     · สีเน้นเพิ่ม signal green #35E08A ใช้เฉพาะ "ข้อมูลที่มีชีวิต" เท่านั้น
       (ค่าที่วิ่ง สถานะปกติ ขั้นตอนที่ผ่านแล้ว) ไม่เอาไปใช้ตกแต่งที่อื่นเลย
     · ขาวยังเป็นพื้นหลัก เข้มเฉพาะ hero กับ traceability ที่ต้องอ่านเป็นหน้าจอ
   สีแบรนด์จากโลโก้จริง: navy #183060 · gold #C09000                            */
