When you told me it worked, I checked on my mobile and saw it had indeed. Then I searched for the page in Chrome on desktop, my secondary browser, and it wasn’t displaying. Went to Safari (fail), then came back to Chrome and probably reloaded and Lo and behold, there it was. Went back to Safari and… now working in Safari too.
Before posting I had of course reloaded multiple times, edited, re-edited… etc.
I’ll let you know when I try applying it all over the place if I bump into anything!
