AMP sites have a 8 seconds-delayed CSS animation on the body element, turning visibility from hidden to visible.
This animation is turned off instantly (as far as I can say) by Javascript. However when you block Javascript entirely or block ampproject.org you have to endure the whole 8 seconds. I inject "body {animation: none !important}" into all pages to remedy this.
It is deemed to have an RNA repair mechanism. This is suggested by analogy with other coronaviruses [1,2] and the length of its RNA of ~30k nucleotides while the upper limit for RNA without repair mechanism seems to be 10k [3]. The german wikipedia cites [4] which I found nicer to read.
