Jumbotron with custom background
jumbotron_background_class controls the CSS class applied to the
<section> wrapping the jumbotron. The theme ships with multiple bg-hero-*
variants; you can also point to a project-specific class for a fully custom
look. This page combines the theme’s bg scaffold with a project-specific
bg-example class defined in docs.css to render a black-to-orange gradient.
jumbotron_background_class: "bg bg-example"
