Can you add a page where its just a list of all of them in a format like that? https://imgur.com/a/iO42lrs

I would love to just scroll through a page without having to click on individual cards to see both side by side.

Love the overall idea of what you did!

Click to toggle. Hard to go back to „old“ version on mobile.

As others have stated, there is no point in a "reveal". Simply show the comparison upfront. User interaction should not be necessary as it only needs to be a plain old html document. You didn't need to write any script. When I got through a bit of it, I wasn't sure if I accidentally skipped something or missed a nuance.

What are you hiding information for? Just show both modes at the same time.

Maybe `ArrowLeft`/`ArrowRight` or `j`/`k` to flip through all of card pairs? Or just allow us to scroll through all the pairs. In either case, both old and new should be visible.
