 * Landing page design system.

 * Editorial/technical direction: a violet-to-amber pair on near-black, generous

 * the hero. Amber is reserved semantically for "this breakpoint was overridden",
 * the same meaning it carries inside the plugin, so the page teaches the colour
 * before the product uses it.
