i took a look and the gifs look ok to me! i don't think i saw any rapid bright flashing, so a gif toggle would be a nice bonus but not a requirement. :> would love to have you on there when you're done though!
yeah, for purely decorative images, alt="" (without any content between the quotation marks) is sufficient
I read something by someone with low vision saying that an empty alt tag made them think the person had just forgotten to leave an alt tag, while a null tag let them know it was something unimportant :0

alt="" *is* the null attribute? leaving it blank would mean not tacking on the alt attribute in the first place.
i think this post was written for people posting on social media platforms that provide an alt text field (in other words, sites that aren't handcoded) - that's where writing "null" would make sense.
for the record that source was recommended to me, so I apologize if it turned out not to be what most people use!
pinkvampyr its kinda hacky, but you detect the user agent for headless chrome and just overlay an image. heres my script if you want it: https://dabric.neocities.org/custom-banner.js
