@foo@domain
syntax which we're going to dub "Yarn Handle" (_unless anyone else has a better name?_)That is a mention of
@prologic@twtxt.net
(_for example_) does a lookup on https://twtxt.net
for a special meta tag of <meta name="yarn-uri" context="/user/%s/twtxt.txt" />
and uses this to automatically expand the mention to its proper Twtxt form of @<prologic https://twtxt.net/user/prologic/twtxt.txt>
👌
