refinedguides/kanban-board — reverse-engineered prompt

Build me a simple Kanban board in plain HTML, CSS, and JavaScript. I want it to feel like a lightweight Trello style task board where I can add tasks, edit them, delete them, and drag them between columns.

Please make the page clean and easy to use, with separate columns for different task stages and a visible task count for each column that updates automatically when I add, remove, or move cards. The drag and drop should feel smooth and work directly in the browser without needing a backend or login.

Keep it as a small beginner friendly project with everything running locally from the files. Make the design polished enough to show in a screenshot, but don’t overcomplicate it with extra features that aren’t needed. If you need to check current browser drag and drop behavior or small implementation details, look up current docs online.
