sdx2 items

Every public item: mass and volume per unit, what makes it, what it goes into. An ore that only becomes one ingot reads on the ingot — dig: ore per unit of ground; refine: ingot per ore, base seconds per ore, ingot per dig. A used line leads with its per-unit rate: ×0.02 = one of this becomes 0.02 of that; the recipe's batch stays in parens. Times are recipe base — machine speed multiplies them. Every name links to its row.
