+   Every figure is the sum of what the chain paid at the time, never today's reward applied to old blocks. "0 IGN" with "no block yet" before the first. The engine carries the windows (section 5.1, item 2); until it does, a window shows its block count only and the IGN reads "reading", and the 24-hour count falls back to `ladder.blocks_24h`, then to the block list, never to zero.
