- Settings 'Size' section: 8 col x 4 row grid, 31 buttons labeled a:b
(a splits H, b splits W); top-left cell empty placeholder (no 1:1 —
title bar double click already maximizes)
- Click resizes the window to work.width/b x work.height/a of the
display's work area (screen_retriever visibleSize, taskbar excluded);
position unchanged, no selection state tracking
- minimumSize 400x300 -> 160x100 (4:8 cell needs it)
- Settings file-properties rows left-aligned (were centered under path)
