   pro/popup.css : ป๊อปอัปยืนยัน / แจ้งเตือนของ i-TEST (ใช้คู่กับ pro/popup.js)
   ------------------------------------------------------------
   ใช้แทน confirm() / alert() ของเบราว์เซอร์ ให้หน้าตาเข้ากับเว็บ (ทอง / ครีม / น้ำตาลเข้ม)
     <link rel="stylesheet" href="pro/popup.css">  <script src="pro/popup.js"></script>
     itPop.confirm({ title: 'ส่งคำตอบ?', html: '...', ok: 'ยืนยัน', cancel: 'ยกเลิก', icon: 'fa-solid fa-paper-plane', tone: 'gold' })
       .then(function (yes) { if (yes) { ... } });
   ไม่ขึ้นกับ .pp : ป๊อปอัปต่อท้าย <body> ใช้ได้ทุกหน้า  ต้องมี Font Awesome + ฟอนต์ Noto Sans Thai ในหน้า (it_head / pro_head มีแล้ว)
   สีตาม tone : gold (ค่าเริ่ม) · ok (เขียว) · warn (ส้ม) · bad (แดง)
   จอไม่เกิน 480px เป็นแผ่นเลื่อนขึ้นจากขอบล่าง ปุ่มเรียงแนวตั้ง
