The nostalgia is architectural, not cosmetic

The app maintains a real 80×25 grid of character cells, blits them from the IBM VGA ROM font into a 720×400 framebuffer, and passes that through a CRT shader. It is a DOS screen because it is built like one.

That constraint is the feature. One document, one screen, no chrome, no formatting to fiddle with. Text wraps at 65 columns: a 6.5″ line at 10 characters per inch, which is an 8.5″ page with 1″ margins, which is what the position readout in the status line is measuring.

Your files stay yours

Plain UTF-8 .txt, anywhere on disk. No proprietary format, no library folder, nothing to export from. Saves are atomic, and every 30 seconds a modified document is copied to a timed backup that never touches your own file. If a backup outlives its document, the next launch offers to recover it.

The keys teach themselves

Esc drops the menu bar; every item shows its shortcut on the right, so the menu teaches the keys and then you stop needing it. Cmd-S, Cmd-Z, and the rest work the way your hands expect. F3 toggles the CRT, F6 counts words, F7 exits, the way it always did.

The name is for whoever is still up past midnight with one lamp on, typing the report nobody else is going to believe.
