sealiee11/arctic-static ? reverse-engineered prompt

Build me a simple static website called Arctic with a clean landing page and a separate embed page.

It should load fast, work well on desktop and mobile, and include the main HTML, some supporting JavaScript, a service worker for basic offline caching, and the small image and SVG assets needed for the branding and favicon. I want the main page to feel polished and minimal, with a nice Arctic themed look, and the embed page to be a lightweight version that can be used inside other sites or previews.

Please make it easy to open and run locally without extra setup, and keep everything self contained in one project. If you need to check current browser support or best practices for service workers and embeds, look them up online.
