Behavior: Produces a full HTML page with dynamically injected Open Graph and social media metadata tags suitable for link previews. The asset can be identified either by a direct asset ID or by a stream URL. When a stream URL is provided without an ID, the asset is looked up by its path in the content bucket. When an ID is provided, it is validated as a share and checked for expiration before rendering. Autoplay can be specified as "true", "false", "1", or "0".

Authorization: No authorization required. This is a publicly accessible endpoint for shared and embedded content.

Side Effects: None. This is a read-only operation.

Error Scenarios: If a share ID is provided but the share is unavailable or expired, an HTML error page is returned. If neither a valid ID nor a resolvable stream URL is provided, an HTML error page indicating the media or share could not be found is returned. Any unexpected errors during rendering also produce an HTML error page.
