Move the fixed width to a class on the parent.

Use className="w-[80px]" on the <div> instead of a static inline style. Remove w-full from MiddleTruncate; layout width belongs on the parent. As per coding guidelines, “No style={{ ... }} or inline <style> for static values a class covers,” and “Layout classes (width, flex, margin, position) belong on the parent.” As per path instructions, “style with Tailwind classes in the component; avoid inline styles for static values a class can express.”

around lines 9 - 10:
Update the parent div in the MiddleTruncate test to use the w-[80px] class
instead of an inline width style, and remove w-full from MiddleTruncate so the
width is controlled by its parent.
