[dune73]

Button primary.html:

<a class="bg-primary hover:bg-primary/90 rounded-lg px-14 py-2 text-white duration-500" href="{{ .href }}">
  {{ .label }}
</a>

highlights.html

         <div class="flex items-center justify-center">
            {{ if (eq (mod $i 2) 0)}}
              {{ partial "components/button/primary" (dict "label" .label "link" .link)}}
            {{ else }}
              {{ partial "components/button/outline" (dict "label" .label "link" .link)}}
            {{ end }}
          </div>

This PR fixes the reference from "link" to "href".
