/* changelog.php page-specific styles. Shared tokens/nav/footer/.btn come
   from landing.css; the .policy-hero/.policy-lead/.policy-body shell
   comes from legal.css (same one security.php reuses). Currently a
   single v1.0.0 release card grouped into categories, not a per-date
   list — kept as its own small file since a future v1.0.x release will
   reuse this same card shape. */

/* Two-column layout: release content + a sidebar list of past releases
   (just the one v1.0.0 link so far — a future entry only needs one new
   <a>). Sidebar goes first in source order on narrow screens (see media
   query) since "which releases exist" is useful before reading the
   current one. No max-width/margin — this already carries the shared
   .container class in markup. */
