Supersized font at one site with 3 of 4 browsers

iPad Mini 5, iOS 26.01. A week or two ago, in the middle of the day the website betanews.com started showing in supersized font in Safari. I checked Chrome, Edge and FF, and all but the latter were (and remain) the same. I've assumed this is a site programming issue, but just to ask here if there's something on the Mini that could be causing it. The site is fine on my Windows 11 PC and no other site has this problem with the Mini.
