Bug: Profile avatar uses nickname and it's overflowing the available space

[sergiozeppo]

Summary

Hey there!
Just decided to register.
Chose the most relevant option for me - via github account.

Problem description

And after login procedure noticed the little bug, I think.
Take a look at profile avatar:

It seems like my nickname is significantly overflows over the available space.
And IMHO it shouldn't be there.

Proposed solution

I propose two ways of solving this problem.

• The first option is to pull up the account icon when logging in via github (as some sites do, e.g. codewars).
  

• The second option is to leave 1-2 capitalized characters instead of the user's nickname (as mail services like mail.ru or gmail does).
  

In my opinion, any of these options would be better than the existing solution.

Reproduction steps

1. Go to "https://runit.hexlet.ru/"
2. Click the "Войти" button
3. Choose the Github logging option
4. Take a look at the profiles avatar
5. Notice the bug.
