/*
 * «نقد و بررسی‌ها» — the reviews section of a product page, and the stars beside the product title.
 *
 * Hairlines, not boxes: the notes are separated by 1px rules so the section reads like a guest book rather than a
 * grid of cards. The stars are two stacked rows — an empty one and a filled one clipped to the rating — so half a
 * star is exactly half, in both directions.
