<p>Blocks arrive as embers from the hearth, one column per miner, and cool as they go: pending molten, included ember, proven bone. A lock is the dark band sweeping up; every block under it is finalised.</p>

<p>Time runs left to right, each miner one step deeper, so parents stand behind their children. The selected chain is the lit spine; a checkpoint is a ring that closes around it when it locks. The camera drifts at chain speed.</p>

<p>The tip is the centre and time runs outward, a ring every 30 seconds. Each miner is a ray; a block is a bead on it that drifts outward, filling when proven. A lock is a ring that hardens from dashed to solid.</p>
