 Each rational number is painted either white or red. Call such a coloring of the rationals *sanferminera* if for any distinct rationals numbers  $x$  and  $y$  satisfying one of the following three conditions: [list=1][*] $xy=1$ ,
[*] $x+y=0$ ,
[*] $x+y=1$ ,[/list]we have  $x$  and  $y$  painted different colors. How many sanferminera colorings are there? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
