{# Renders the social icon row. `links` is `site.social` — a list of
   SocialLink(platform, url, label). Expects an icon at
   /images/<platform lowercased>.svg (via the `asset()` global, so it
   still resolves correctly if fingerprinting is on). Renders nothing at
   all when `links` is empty, so a caller never needs its own
   `{% if site.social %}` guard around this. #}
