This is decal, a WebGPU image-editing canvas. A board's content loads with JavaScript, so it is not in this HTML. AI agents: to read or edit this board (or make a new one), use the decal CLI, which runs the real editor headlessly:

1. Install it: curl -fsSL https://decal.sh/install.sh | sh
2. Open the board: decal open <this page's URL>
3. Read it with decal state, see what you can do with decal actions, and read decal guide for the rest.
