Shapes, sticky notes, text, frames, edges, images and freehand ink — the core board, with no rich-text editor and none of its dependencies.

The same board with BlockNote block-editor nodes added through the opt-in entry point.

Three custom node types wired into a live data-flow graph — typed ports and a pure compute function, recomputing as you drag.

The development app: around forty custom node types, plus the Whiteboard, Half adder, Deck, Summit day and Mission Control boards.
