at least two problems:

1. indieauth fails for @Zegnat because he uses his own auth endpoint, https://vanderven.se/martijn/auth/ , which we somewhat handle ok, but its verification response doesn't return me, which we don't handle ok. IRC discussions, snarfed/oauth-dropins@d65d415, snarfed/oauth-dropins@f8ff52e.
2. when i try to log in, indieauth works ok, but then the IG profile page fetch gets rate limited, which breaks badly with an IG-rendered error page 😂 😭.

apologies @Zegnat, but i may deprioritize 1 until if/when you actually use bridgy. 😆 2, though, i should look at.
