every part of this page comes from metamatt.io. no outside
company's code runs here, so there is nothing to count you or
recognize you.
pick one of the three and your browser just goes there. nothing
here writes down which one.
the computer that sends you this page writes a line in its log,
with your IP address in it. every website does that. it is the one
record here nobody can switch off.
your browser keeps one small note, metamatt.arrival,
so the opening is quicker next time. it never leaves your device,
and replay arrival clears it.
