Building wideboi for Ultrawide and Ultrasmol Terminals

TL;DR: What started about ten days ago on a whim as an experiment in horizontally scrolling terminals across an ultrawide monitor turned into wideboi—a terminal multiplexer with animated cards, an embedded web UI for phones, a desktop app, and a headless control surface for AI coding agents. This really didn't need to get made, except that I wanted to make it. Overlapping live terminals go zoop zoop zoop The Ultrawide Problem I have an ultrawide monitor on my desk. Most terminal multiplexers—tmux, screen, zellij—seem convinced that monitors should be divided like graph paper. You split horizontally, you split vertically, you split again, and before long you're squinting at four 35-column slits where every shell command wraps into unreadable soup. What I actually wanted was something much simpler: I want to have a bunch of terminals running at comfortable, readable widths, go zoop zoop zoop between them with a keystroke, and vaguely see them chattering away while I stare off and…
