/**
 * The opening section of a landing page: an optional eyebrow, the page
 * title (the only `<h1>` among the blocks), a description, actions and an
 * optional media slot. Every piece of content is a prop with a neutral
 * default, so `<Hero />` renders a complete example.
 *
 * With `media` and `align="start"` the text and the media sit side by side
 * on large screens; centred, the media goes under the text in a rounded,
 * bordered frame. The alignment is exposed as `data-align` for restyling.
 *
 * Accessibility: keep one `<h1>` per page, so use a single Hero. Give
 * images in `media` an `alt` text, or `alt=""` when they are decorative.
 *
 * @example
 * <Hero
 *   title="Plan, track and ship"
 *   description="One place for your roadmap, issues and releases."
 *   media={<img src="/screenshot.png" alt="The Acme dashboard" />}
 *   align="start"
 * />
