# Plots 4,5,6 are adjacent in block A (row 1: 4,5,6)
# Plots 7,8,9,10 are adjacent in block A (row 2: 7,8,9,10)
# Plots 1,2,3 are adjacent in block A (row 0: 1,2,3 — but 0 is None)
# So: 4 adj 5, 5 adj 4&6, 6 adj 5
#     7 adj 8, 8 adj 7&9, 9 adj 8&10, 10 adj 9
#     1 adj 2, 2 adj 1&3, 3 adj 2
#     4 adj 8 (vertically: row1col1=4, row2col1=8... wait no, 4 is at (1,1) and 8 is at (2,1))

# Let me verify: _GRID row 1 = [None, 4, 5, 6], row 2 = [7, 8, 9, 10]
# So 4 is at col1, 8 is at col1 in next row → 4 adj 8
# 5 adj 9, 6 adj 10
# 7 adj 8 (horizontally), 8 adj 7&9 (horizontally) + 4 (vertically)
