how it works.

The banner uses the accent color as its background-color directly rather than as a small highlight, which flips the usual balance and makes it a strong final prompt before a page ends. Its layout is a flex row with justify-content space-between so the message sits on one side and the button sits on the other, collapsing gracefully onto two lines with flex-wrap wrap on narrow widths. The button inside inverts the usual color scheme by using a white background-color with accent colored text, which keeps it readable and prominent against the solid colored banner behind it. Border-radius is applied to the outer banner so it can be dropped into a page as a rounded rectangle section rather than a full bleed strip. A subtle hover effect using transform scale on the button gives it the same tactile feedback style used by buttons throughout the rest of the library.
