limitless-soul1/sard ? reverse-engineered prompt

Build me a desktop ebook reader called Sard for Windows that feels calm and minimal, with a single centered reading page and the rest of the window getting out of the way.

It should let me import EPUB and PDF files, keep my library local on my machine, and remember where I left off. I want a polished library view with covers, shelves, sorting, filtering, and a few different ways to browse. The reader needs to handle both Arabic and English really well, with right to left support, mirrored layout, proper typography, and the ability to show, dim, or hide diacritics.

Please include search that works without being spoiled by future content, highlights, notes, bookmarks, and a way to tweak reading appearance like fonts, spacing, margins, colors, and themes. If possible, add read aloud support, offline if you can, and make it all feel smooth, lightweight, and privacy friendly. Look up current docs online if you need to.
