StructuredLabs/preswald ? reverse-engineered prompt

Build me a small Python tool for making interactive data apps that run entirely in the browser and can be exported as a single shareable file.

I want the app to let me load a CSV or similar data file, show a clean dashboard with a table and a few charts, and update the view when I change filters or inputs. It should feel like a lightweight report or notebook that works offline, with no setup for the person opening it.

Please make it easy to start a new app, run it locally while I edit it, and then export it to a static version I can share with someone else. Use simple branding settings, support a basic config file, and keep the code organized so it is easy to extend with more components later.

If you need to look up the latest docs online, go ahead.
