mult1v4c/hestia-core ? reverse-engineered prompt

Build me a browser based homelab dashboard like Project Hestia, with a modular grid layout that I can drag around, resize, and save automatically. I want it to feel polished and customizable, with strong theme support, custom colors, spacing, fonts, corner rounding, shadows, and the ability to save and reuse presets in the UI.

It should include useful built in widgets like a clock, weather, calendar, notes with markdown, bookmarks, server stats, Pi hole, Deluge, Jellyfin, and some fun visual widgets like image frames, matrix rain, and a retro screensaver style effect. Let me add my own widgets too in a simple way.

Store the layout and settings locally so there is no database, and make it possible to export and import the full dashboard config for backup. If needed, look up current docs online for anything that helps with browser APIs or the integrations. I’d like it to work well in Docker too, with a simple way to proxy the API calls and avoid CORS issues.
