[Jan_Lukas_Else]No, I use Alpine Linux on the server and I think it was just a matter of changing a config file to get an IPV6 address and add a reverse DNS entry in Hetzner Cloud Console.
petermolnarjeremycherfas: I am, unfortunately, aware of the label vs image width. I wanted to avoid using js for that gallery, and so it's pure CSS. Trouble is, the image sizing in CSS is kind of a mystery, because, unlike the label, it has a height limit as well; as a result, the width parameter is not trivial. I am yet to figure out how to size the label correctly to follow the image size.
petermolnar[grantcodes]: In the h-entry div there's a h3 for the title and the link, and a figure with an img inside. The gallery css sets the whole thing to be a flexbox, with limit on the h-entry width. simultaneously there's a max viewport height % on the image, making it fit nicely into any orientation and aspect ratio.
petermolnartrouble is that now the img width is unknown to the sibling and I can't make the parent follow it either, because then the flexbox collapses
