Basic board
The slim core board — shapes, sticky notes, text, frames, edges, images and freehand ink, with no rich-text editor and zero BlockNote peers.
Opt-inRich text
The same board with BlockNote block-editor nodes added through the
spatialboard/blocknote entry point.
Custom nodes
Three custom node types wired into a live data-flow graph — typed ports and a pure compute function, recomputing as you drag.
EverythingPlayground
The development app: every feature, around forty custom node types, plus the Whiteboard, Half adder, Deck and Mission Control boards.
