This is fascinating, but I was curious about the last two QR codes. The left one is scannable on my iPhone (iOS 17.4.1) leading to http://example.com/AAE..._w8fL whereas the one on the right gets only http://example.com (both Safari and Firefox). Is this an iOS URL length limitation?

Good catch! I should've tested. I've added a paragraph to https://huonw.github.io/blog/2024/03/qr-base10-base64/#extre... about this.

You probably know this, but Firefox and Chrome don't have the freedom to run their own browser engines on iOS and are little more than browser skins around the webkit core, so listing multiple browsers for a web issue on iOS usually doesn't mean much.
