Build the end matter of a blog article with Tailwind CSS: after the last paragraph, a share rail with copy-link and social buttons where copy-link flips to a "Link copied" confirmation, an author card with avatar and follow button, a tags row, and a "related posts" three-up grid with cover images. Include a newsletter signup strip between the author card and the related grid, and mark the whole block with a top border so it reads as a distinct footer zone.
