Modules
module	four_center_integral_preparation
	Gaussian-product geometry and radial seeds shared by four-center evaluation and screening.

Functions/Subroutines
subroutine, public	four_center_integral_preparation::prepare_eri4_pair (ra, rb, zeta, zetb, rab2, pair, image)
	Prepare one Gaussian pair, retaining the caller's image topology and screening metadata.
subroutine, public	four_center_integral_preparation::prepare_eri4_product (pair_a, pair_b, m_max, product)
	Prepare the image-independent quartet data once per combination of Gaussian pairs.
subroutine, public	four_center_integral_preparation::prepare_eri4_primitive (product, image_a, image_b, attenuation, pq2, potential_parameter, params)
	Complete a prepared quartet for one selected image, including normalized radial seeds.
