Just one variant, that's refreshing. And performance is impressive. What's the short input performance like? Say for 64 bytes of input.

  The Performance section of the spec (https://github.com/BLAKE3-team/BLAKE3-specs/blob/master/blake3.pdf https://github.com/BLAKE3-team/BLAKE3-specs/blob/master/blak...) has a paragraph about short input performance. 64 bytes happens to be the BLAKE3 block size, and performance at that length or shorter is best in class. Look at the left edge of Figure 3 (https://i.imgur.com/smGHAKA.png https://i.imgur.com/smGHAKA.png).

    64 bytes happens to be the typical cache line size so it makes sense to use it as a block size.

    What about padding?
