Finally managed to get around to convert my 11ty contact form to use a Cloudflare email worker, Resend, and reCAPTCHA v3. May just have to write it up as a blog post "soon" (now on the to-do list!)

My wife had to explain to my autistic son that he still needs to put on his new deodorant every day, even though it says 19hrs protection. Since a school day is only 6 hours, he hadn't put it on for 3-days! 😱🫣

I think something has gone a little wrong for "Which?" on their Google search results 😬 JS error, maybe? or "application/ld+json"? Can't see any mention of it in the source, so it must have been fixed 🤷♂️
