shreyansh6726/NotesVault ? reverse-engineered prompt

Build me a Notes Vault web app where people can sign up, log in, and manage a sticky note board that feels interactive and fun.

I want users to create, edit, drag around, and delete notes on a board, with note positions saved so the layout comes back after refresh. Notes should support custom colors, tags, search, and filters, plus sharing with other people by email. Make the board feel polished with smooth animations, different background themes, and a right click menu for quick actions. I also want some advanced note types like checklists, passwords for private notes, due dates, a recycle bin and archive, revision history, voice memos, image uploads, and a simple sketch area for drawing ideas.

Please also add useful extras like snap to grid, keyboard shortcuts, zoom controls, and the ability to export the board as an image or export a note to PDF. Keep the experience clean and easy to use, and if you need current implementation details, look up the latest docs online.
