I love this. Great little html page to refresh on Javascript.

For fun I put it in chatgpt and asked if there are bugs.

It warned about fromBase64() and toBase64() not existing in main browsers. It is supported but is indeed a new "baseline 2025"feature. It suggested more compatible code using two small functions to convert characters manually.

"deflate-raw is not consistently supported." It suggested using 'deflate' instead.
