Rewrite toy office : free-form db app

Toy Office was a Rails app using obsolete front-end tool Hobo. I had dropped the project because rendering many DOM object with many input fields was taking forever.

I also wonder if Vite.js could speed up the rendering.

Here is a youtube demo of the most basic features.

And another about the philosophy behind the app, originally targeted at investors.
