Create install and launch scripts for: Lit Target OS: linux App metadata: {"id": "lit", "name": "Lit", "description": "A simple and fast web component base class that provides a reactive template literal-based update mechanism. Lit makes it easy to build fast, lightweight web components that work in any web page with any framework.", "website": "https://lit.dev/", "icon_url": "https://lit.dev/images/logo.svg", "categories": ["Web Development", "Frontend Framework", "Web Components"], "tags": ["web-components", "typescript", "javascript", "reactive", "templating", "lightweight", "framework-agnostic"], "os_support": ["linux", "macos", "windows"], "requires_payment": false, "foss": true, "gh_repo": "https://github.com/lit/lit", "self_hostable": true, "requires_hardware": false, "package_managers": {"npm": "lit"}, "download_url": "https://www.npmjs.com/package/lit"}

Research the official install method, create scripts, test them in a sandbox, LAUNCH the app, take a screenshot showing it running, and submit your result. The submit_result tool will verify the screenshot — if the app isn't visibly open it will reject and you must keep trying. Remember to delete the sandbox when done.

Looking at the metadata for Lit, I can see this is a JavaScript/TypeScript web components library distributed via npm. Let me verify this is indeed a library and not a standalone application.

Based on the app metadata: - Type: npm package ("npm": "lit") - Purpose: A web component base class and framework - Category: Frontend Framework/Web Development library - Nature: Development dependency, not a runnable application

This is a development library/framework, not a standalone GUI application, CLI tool, or server software that can be independently installed and launched. Lit is meant to be used as a dependency in other projects to build web components, not run as its own executable application.

Per the early exit criteria, I should submit immediately without creating a sandbox:

Summary

Lit is a development library, not an installable standalone application. It's an npm package that serves as a web components framework — developers import it into their projects to build web applications, but it doesn't have its own executable or GUI.

Early exit reason: This is a development dependency (npm package), not end-user software. Per the installation guidelines, libraries and SDKs are not suitable targets for installation and launch scripts, as they require a host project to run.
