[Suggestion] Save the board geometry preference to user account

I have set the firefox setting to delete cookies and site data when it closes so every time i sign into lichess i have to reset the board geometry because it has returned to default size

It would be nice if it was stored like the theme preference for example which i only set once a couple of years ago and it has never returned to default since

thanks

It's better if you don't delete your cookie. Storing geometry in the account means the same settings on every device.
