meltedkeyboard/imgbrowser — reverse-engineered prompt

Build me a fast, minimal desktop image viewer called imgbrowser.

I want it to open either a single image or a whole folder. If it opens a folder, show a thumbnail filmstrip at the bottom so I can browse images quickly. If it opens one file, keep the interface clean and hide the filmstrip. Support JPG, PNG, WebP, GIF, and BMP.

The viewer should let me zoom smoothly with the mouse wheel, drag to pan, fit to window, view at 100 percent, rotate left and right without changing the original file, and go next or previous with simple keyboard shortcuts. Add fullscreen, drag and drop for files or folders, an EXIF info sidebar, and a delete action that moves the current image to the system trash after confirming.

Please make it cross platform on desktop using Go, keep it lightweight, and include a simple toolbar with buttons for common actions plus an about dialog. Look up current docs online if you need to.
