Short disclosure: The footer contains one industry link to Oscar Pergola with the anchor text “pergola”. It is qualified with sponsored and nofollow relationship attributes and carries no editorial-ranking promise.
Editorial separation
Oscar Pergola is not used as evidence for code, test or engineering conclusions. Article source tiers, findings, comparison dimensions and warnings do not change because of the link. The site currently publishes no paid product rankings and does not disguise commercial pages as encyclopedia entries.
Why the link remains
The link remains as a disclosed industry relationship requested by the site owner. Because it appears in the site template and uses a keyword anchor, it is clearly labelled and qualified with Google's recommended relationship attributes rather than represented as an independent organic editorial endorsement.
