No metadata for link previews

## Issue
While sharing a link to https://launchpad.ethereum.org it was noted that the share link did not come with any metatags to preview the link

## Screenshot

Example of sharing the link with no preview being displayed.

## Expected result
When sharing a link to the launchpad, we should have an og-image, title and description (page metadata) to provide a clean sharing experience.

The issue points to the launchpad URL but names no repository file or test. Start by locating the page entry point that renders https://launchpad.ethereum.org and inspect its existing head metadata; done means the rendered page exposes an og-image, title, and description suitable for link previews.
