Pave loading system
The iterations
The first passes turned product features into moving icons. The useful version removed the puzzle: fixed cells only light, dim, or change colour; white leads and green trails.
The chip follows the work
The UI recording keeps meaning in the host: Implement core changes is the active tool verb; Waiting for your approval pauses ordinary loading; Disconnected names a connection condition, not failure.
Finish from the frame you have
Completion begins from the lit cells already on screen, floods outward, retracts the grid, then resolves to the Pave mark. That made it possible to finish an interrupted motif without pretending the earlier frame did not happen.
