Part 1: the kanban board (lanes, one name per card, the 3-line sync). Part 2: a free Vercel account and your app live at a real URL.
Yesterday you became a company. Today you learn the thing that kills more student teams than bad code: four people crowded around one laptop, three of them watching. You will split your product into lanes, put every task on a board with exactly one name on it, and learn the 3-line sync that keeps a team moving without a manager.
A coding agent makes building cheap. The bottlenecks now are coordination (who does what) and visibility (can anyone actually see it?). The kanban board fixes the first; a real URL fixes the second.
