# Visual Sudoku preprocessing
# Generation parameters are hardcoded in SudokuPreprocessor to avoid extra
# DatasetConfig fields.  Current values:
#   n_clues_start = 55   (start with 55 random clues — almost always unique)
#   max_removals  = 10   (remove up to 10 clues while preserving uniqueness)
# Result: ~45 clues per board, all uniquely solvable, no warnings.
# For publication: increase max_removals to get true minimal puzzles (~25–35 clues).
