chriz-3656/PDF-studio-pro ? reverse-engineered prompt

Build me a browser based PDF editor called PDF Studio Pro that runs fully on the client side, so people can work on PDFs without uploading them anywhere.

I want a clean dark mode interface with a modern glassy look, and the main flow should let someone open a PDF, create a blank PDF, and edit pages directly in the browser. They should be able to add text, move it around, change font, size, and color, drop in images, draw freehand, and add simple shapes and annotations like highlights, underlines, lines, arrows, rectangles, and circles.

It should also support page management like adding, deleting, rotating, and reordering pages with thumbnails. Please include form fields like text boxes, checkboxes, and radio buttons, plus options to merge and split PDFs and basic password protection or print and copy restrictions. Make it feel polished and responsive, and if you need current docs for the PDF libraries, look them up online.
