fix layout: same nested-link + grid track collapse fix as hype/viralmvp

PostList no longer wraps cards in an outer <a>, so .post-hero-link
and .post-row-link selectors don't match anything. Layout now grids
.post-hero and .post-row directly + adds the stretched-link pattern
on .card-link inside titles + min-width: 0 on grid items + tag link
z-index: 2 above the title overlay.

No design changes — same vermilion + cream Chinese magazine palette.
