Same event data
Full page and modal receive the same event object before rendering.
Intercepting routes
Modal vs full page
Same event data can appear as a full SEO page or as a compact modal preview, depending on how the user enters the route.
Full page route owns metadata
The direct event URL keeps generateMetadata, canonical, hreflang and share previews.
Modal route owns quick preview UX
The intercepted route renders inside @modal and stays focused on the list browsing flow.
One component, two modes
EventDetails keeps the existing JSX in one place while routes provide different actions.
