kenforthewin/atomic-editor ? reverse-engineered prompt

Build me a React markdown editor with the same feel as Obsidian, where the formatting shows up inline as you type, but the underlying text stays plain markdown the whole time.

I want headings, bold, highlights, links, images, tables, task lists, and wiki style links to all render nicely inside the editor without a separate preview pane. Clicking into text should reveal the raw markdown only on that line, then hide it again when I move away. It should also have a read only viewing mode that keeps everything rendered like a document, while still letting me click links and toggle checkboxes.

Please make it smooth with large documents, support syntax highlighted code blocks, a simple find box, and a clean theme that can switch between dark and light. If anything needs current docs or examples, look them up online and follow the best modern approach.
