Miru — Grid Image Viewer
=========================

Overview
--------
Miru is an image viewer that displays multiple images in a customizable grid layout.
Each row can have a different number of columns, and the entire window is always
filled with image content — no toolbars or wasted space. A dedicated Manga Mode
provides two-page spread viewing for comics, photo books, and similar content.

Supported OS: macOS / Windows
Supported formats: JPEG / PNG / BMP / GIF / TGA / WebP
