Module nxwin 

NeXTSTEP window chrome for in-app floating windows (spec §3, §4.3, §5).

NxWindow wraps an [egui::Window] that has no egui title bar or frame, and paints the NeXT chrome itself: a 1 px black border, a 23 px title bar (black when key, dark gray otherwise), a beveled close box, a bottom resize bar split into thirds, and a light-gray body. Every piece is a painter shape; the only glyphs are the title text.

The key window is the most recently clicked NxWindow, tracked in egui memory; see is_key. Closing the key window hands the key to the next window shown.
