SUBHAM-RAJ-X/Pipeline-Drag-and-Drop ? reverse-engineered prompt

Build me a simple pipeline builder where I can drag items onto a canvas, arrange them visually, and connect them together to make a flow.

I want it to feel easy to use, like a small app for creating and viewing workflows. Include a clean interface, a list of available blocks or steps to drag from, a workspace where I can place them, and the ability to connect steps so the pipeline makes sense. If it helps, add basic validation so invalid connections are prevented and make sure the layout stays tidy when I move things around.

If the project needs any backend support for saving or loading the pipeline, add that too in a simple way. Keep the design polished and responsive, and if you need to check current docs or best practices while building it, go ahead.
