   Task 2A: Bàn oval + seat positions
   ═══════════════════════════════════════════════════════

   Seat positions (% từ top-left của .th-table):
     Mình (seat mình) luôn ở dưới cùng giữa — không có slot,
     được render trong .th-self-area bên ngoài bàn.

   Seat slots đánh số theo chiều kim đồng hồ:
     data-seat="0" → trên cùng giữa
     data-seat="1" → trên phải
     data-seat="2" → phải giữa
     data-seat="3" → dưới phải
     data-seat="4" → dưới trái  (ít dùng — self thường ở đây)
     data-seat="5" → trái giữa
     data-seat="6" → trên trái

   Vị trí % được tính theo ellipse 90%×80% center tại (50%, 46%)
