   Rental-Pro — ธีมหลัก (dark + blue)
   ---------------------------------------------------------------------
   หลักการ:
   1) ห้าม hardcode สีในหน้าเพจ ทุกสีต้องมาจาก CSS Variable ใน :root
   2) เขียน CSS เพิ่มเฉพาะสิ่งที่ Bootstrap 5 ไม่มี
   3) ทุก element ที่กดได้ต้องมี hover / focus / active ที่ชัดเจน
   4) ใช้ transform / opacity / box-shadow เท่านั้น (ไม่ขยับ layout)
