Fluid Intelligence Peak

Fluid Intelligence Peak extends the Raven's Progressive Matrices paradigm toward its harder, more novel end — the family of "distribution of three" rules, where a Latin-square arrangement means every row and every column contains the same three values, just never in the same order. Recognizing this rule requires checking a grid two ways at once (across the row AND down the column), which is genuinely harder to spot than a simple row/column constant, and closer to what fluid intelligence research means by reasoning that doesn't reduce to a memorized rule.
