feat(header): highlight active nav link with bold + underline
Compares the link href against `$page.url.pathname` (with trailing-slash normalization + subpath match), applies `font-bold underline` and `aria-current="page"` on a match. Wired into both the desktop horizontal nav and the mobile slide-down menu. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
