    css: Import GTK 4's General Typography section
    
    Previously, just two of these (.title-1 and .caption) were imported. A
    subsequent commit will use a few more. Import the whole lot so we can
    use them as needed, and update the comment to reflect the fact that
    "eventually" has arrived, just not reached GNOME Software yet.
