    application: Apply custom styles in HighConstrast
    
    HighContrast and HighContrastInverse have been poorly supported in
    this app for a long time because we ship many custom styles.
    
    However, nowadays HighContrast and HighContrastInverse stylesheets
    are derived from Adwaita stylesheet, so the same custom styles
    can be applied cleanly. Let's do that.
