its nice to see inline srcset however what are we doing here? future proofing -site for a time when jpgxl's are more widely supported when its going to be replaced shortly? if we had translations set up we would be presenting translators with alot of raw html. replacing the screenshots with new avifs is perfectly acceptable.

I'd much rather see your efforts and knowledge put into how we should be displaying images in astro / discussing fallbacks/image types with the new designer/dev.

yes, JPEG XL has more features and looks more freer format*, that's why I preferred over AVIF.

In my testings:
AVIF performing better for more lossy pictures
JPEG XL performing better for less (or lossless) pictures

there's more detailed comparison: https://cloudinary.com/blog/time_for_next_gen_codecs_to_dethrone_jpeg

converting to ready for review, IOS screenshots can be fixed with different PR

NACK - remove the srcset busy work.

Would like someone to update the iPhone screenshots. I asked in monero-site matrix.

unfortunately, i dont have an ios device. Also, since element doesnt allow multiple accounts.. a user will have to logout from their matrix if they want to screenshot the setup.

Approving anyway.

Apparently iOS screenshots look the same as Android's so @HardenedSteel is suggesting we skip those and just use Android's.
