The area around the "sign in" and "sign up" buttons in the header switches the cursor to the hand, implying you can click, but only the button itself is actually clickable. This is confusing.
This ought to be a simple matter of CSS or HTML, but I tried looking at the code and the style sheet and was defeated. The relevant places seem to be app/views/layouts/_header.html.erb and app/assets/stylesheets/application.scss (search for header--item), but I'm not sure what to do from there to find and adjust either the bounds or the click zone, sorry.
