Two designers, one canvas, both cursors visible

Desktop design tools were built for one chair. Pairing on them means screen-share narration: "no, the other panel: up: your other up."

On a shared display, both of you open the same URL with ?sharing=true&steal=false. Same Inkscape, same file, same desktop. You adjust the type while your colleague nudges the grid; cursors show who's doing what, input is serialized one keystroke at a time, and every change appears for both of you instantly. When the icon set is done, it's done once, in one place: no "send me your version" merge at the end.

This is the single-player application your team already knows, made multiplayer by its URL.
