I've previously set out some styling for text hyperlinks as part of the ORCID style guide. It'd be great if we could have these set up as the defaults for the registry app across the board.

We should, at the very least, have the full set of link states in place for each and every link/button. I recognise that this will affect things like the 'Print version' link by changing the colour, making the text larger and adding an underline.
