feat: add the showcase page and link to it from the home page #1

	name: Showcase

	# Each showcase image is a URL that the site reads at view time, so the check
	# downloads every image to read its type, size and dimensions. It needs the
	# network, so it is not part of `yarn verify` and runs only when the showcase
	# changes: a host that is down must not fail an unrelated pull request.
	# ci.yml still typechecks and lints every entry.
	#
	# Action pins follow ci.yml: a commit SHA, with its tag in the comment.
