[Copilot]

rel="me" is intended for identity verification and generally only works reliably when linking from the verifying site to the profile without target="_blank" semantics; some verifiers are strict about the exact link relation and/or the browsing context. Consider only adding target="_blank" (and noopener noreferrer) for non-rel_me links, or make target_blank configurable per-link in the data so the Mastodon link can omit it while preserving the behavior for other links.

	<i class="{{ link.icon_class }}" aria-hidden="true"></i>
	</a>
	{% if link.rel_me %}
	<a href="{{ link.url }}" rel="me" aria-label="{{ link.label }}" title="{{ link.label }}">
	<i class="{{ link.icon_class }}" aria-hidden="true"></i>
