// MegaMenu -- a trigger and a wide panel of grouped links.
//
//   <MegaMenu label="Products" columns='[{"heading":"Platform",
//     "items":[{"label":"Runtime","href":"/runtime"}]}]' />
//
// Deliberately one level deep. A mega menu exists to show breadth flat, so
// everything is one click away; nesting inside the panel buries content behind
// hover-within-hover and is close to unusable by keyboard and touch. Use Nav
// when you actually want cascading submenus.
//
// The panel carries data-wrn-anchored so the runtime clamp keeps it inside the
// viewport instead of hanging off the edge of a wide layout.
//
// NOTE: the style block uses /* */ comments only -- // is not a CSS comment
// and silently swallows the rule that follows it.
