## Description

Tableaunoir is an online collaborative blackboard tool designed for teaching. It features fridge magnets — movable images, text, and numbers — for creating interactive animations to illustrate algorithms, graphs, and other concepts. Users can draw and erase with a graphics tablet or mouse, collaborate in real-time on shared boards (requiring a Node.js websocket server), and export boards to PNG or PDF. It supports LaTeX via MathJax, Markdown, code highlighting, multiple backgrounds (blackboard, whiteboard, music staff, grid, PDF documents), slide/animation recording, interactive graphs where vertices are magnets, and left-handed mode. The app runs in any browser, can be used offline via Electron or by opening index.html directly, and requires no user accounts. The front-end is served by nginx or Apache, while the optional websocket server runs on Node.js (default port 8080).
