Section usage
Hero, navbar, cards, footer.
Hero
Keep the background calm and let the CTA carry the strongest color.
Navbar
Use the darkest shade for navigation and the accent for the active state.
Cards
Cards stay readable when the accent is limited to icons, tags, or buttons.
Footer
A quieter support shade gives the page a softer ending than the hero.
