Switch the original theme to a red background with white message text, with
navy buttons, evoking the red B07/B99 stock. Red/white/blue are all retained.

Use a cream/white background with navy message text and red buttons, so the

Single-page layout with a centred message, a colour-scheme toggle, and a
"Check again" button. styles.css defines two palettes selected via the

red-and-blue livery.
