pablostanley/squig ? reverse-engineered prompt

Build me a browser based wireframing app like squig, where I can think by drawing on an infinite canvas and drag in real UI pieces that look hand drawn instead of polished.

I want the usual whiteboard style stuff like pan, zoom, select, multi select, undo and redo, snapping, copy paste, and keyboard shortcuts that feel natural. The app should have a left side library for components and blocks, a right side inspector for changing variants and settings, and a search palette that lets me quickly find tools and insert things into the canvas. I also want to be able to paste screenshots or text into the canvas, keep everything saved locally in the browser, and export a copy when I need to.

Make the whole thing feel sketchy and loose, like a napkin draft, not a finished mockup. If you need to, look up current docs online for any libraries or patterns that help.
