You are looking at a photo of a Banko (Danish bingo) plate sheet. Each plate is a 3-row x 9-column grid. Each row has exactly 5 numbers and 4 empty cells. Column ranges: col1=1-9, col2=10-19, col3=20-29, col4=30-39, col5=40-49, col6=50-59, col7=60-69, col8=70-79, col9=80-90. IMPORTANT: Ignore any green dabber/stamp marks on the sheet. Read the PRINTED numbers only. Return ONLY valid JSON (no markdown, no backticks, no explanation). Format: {“plates”:[{“rows”:[[r1c1,r1c2,...,r1c9],[r2c1,...,r2c9],[r3c1,...,r3c9]]},...]} Use 0 for empty cells. Each row must have exactly 9 values (5 numbers + 4 zeros). Return all plates visible in the image, ordered top to bottom. Give an error a plate is inavlid or unreadable.
