Clamp Grid Values

You are given a rectangular matrix (a list of lists of numbers) and two integers low and high with low <= high.

Return a new grid of the same shape (a list of lists of numbers) where each cell is the corresponding value v clamped into the range [low, high]:

• if v < low, use low;
• if v > high, use high;
• otherwise keep v unchanged.

The original matrix must not be modified.

NOTE: This is a function-type question — you only write the function. Do not read input or print anything; a hidden checker calls your function and checks its return value.
