	## Container Images

	Two variants are built for different use cases:

	### talos/cozystack-spin-tailscale (Full Stack)
	Includes Spin runtime + Tailscale networking for complete demo environment.

	\`\`\`bash
	docker pull ${{ env.REGISTRY }}/talos/cozystack-spin-tailscale:demo-stable
	\`\`\`

	### talos/cozystack-spin-only (Minimal)
	Includes only Spin runtime for lightweight deployments.

	\`\`\`bash
	docker pull ${{ env.REGISTRY }}/talos/cozystack-spin-only:demo-stable
	\`\`\`

	## Asset Extraction

	Extract complete Talos installer assets:

	\`\`\`bash
	# Create local assets directory
	mkdir -p ./cozystack-assets

	# Extract from talos/cozystack-spin-tailscale image (recommended)
	docker create --name temp-extract ${{ env.REGISTRY }}/talos/cozystack-spin-tailscale:demo-stable
	docker cp temp-extract:/. ./cozystack-assets
	docker rm temp-extract

	# Key assets are located at:
	# ./cozystack-assets/usr/install/arm64/vmlinuz.efi
	# ./cozystack-assets/usr/install/arm64/systemd-boot.efi
	# ./cozystack-assets/usr/bin/installer
