    Select a representative color for a quantized cell, honoring transparency.

    If at least ``majority_fraction`` of the cell's pixels are transparent
    (alpha < alpha_threshold), the cell becomes fully transparent (0,0,0,0);
    otherwise it takes the most common RGB color at full opacity (R,G,B,255).
