OGN

Every node owns its grid lines.

One horizontal grid line and one vertical grid line belong to the node. No other node may use either line.

A position is free when both grid lines are free.

Writing a node occupies one horizontal line and one vertical line.

ABC A, B, C: separate rows + columns · dashed: free positions

After writing a node, both of its grid lines are occupied.

Write one node. Update the grid. Repeat.

Every step starts from the occupancy created by all earlier steps.

The first valid candidate found is written immediately.

The renderer draws the selected position. It does not silently choose another one.
