martinargalas/ha-arr-stack-card ? reverse-engineered prompt

Build me a Home Assistant dashboard card for a media server stack that pulls everything into one clean view. It should show the main services like Radarr and Sonarr, plus download clients, request apps, subtitle status, streaming apps, stats, and recommendation tools, and only display the services that are actually set up. I want it to feel easy to use in Lovelace, work well on mobile and desktop, and let me manage things like downloads, requests, and stream status from one place instead of jumping between apps.

Please make it look polished and modern, with useful icons, status indicators, and a layout that makes the important stuff easy to scan at a glance. If there are setup steps or config options needed, keep them simple and beginner friendly. Also include a clear fallback for poster and media details, and if you need to check current Home Assistant or HACS docs online, go ahead and do that.
