delmoonkarn/del-image-reader — reverse-engineered prompt

Build me a local desktop manga and comic image reader for my own folders.

I want to choose a root folder on my computer, have the app scan all subfolders, and show any folder with images as a chapter or collection. It should feel like a modern manga website, with cover thumbnails, breadcrumbs, search, sorting, tag filters, page count filtering, and a random pick button that respects the filters.

The reader should support single page, two page spread, and vertical scroll modes. Please add keyboard controls for next and previous page, fullscreen, changing view mode, and a page jump menu. When I go back to the gallery, it should remember where I was scrolled.

Everything needs to stay local. No uploads, no server. Cache the scanned library so it opens fast next time, with manual rescan and reset options. Also support reading and editing Windows image tags from JPEG cover metadata, and keep those tags with the files if possible.

Use the existing TypeScript desktop app setup, and look up current docs online if needed.
