After building my UI, I gave my UI to a person to test. At the input Textfields, he stopped bewildered. The boxes looked set to NOT editable or disabled. Some else at a review mentioned the same thing. Please make the border darker or do something else so it does not appear disabled!
I tried pulling this out from caspian.css and changed to the following and pasted it into a css file in my src directory, but it made no difference.

root {
       /* Darker than -fx-background and used to draw boxes around text boxes and
     * password boxes.
     */
    -fx-text-box-border: ladder(
        -fx-background,
        black 10%,
        derive(-fx-background, -75%) 90%
    );
}
