Storage Container

It absorbs timing differences between a producer, hand-sorted stock and a launch or build target; it does not fix a belt or machine bottleneck.

When it fits: Use it at a handoff where a short reserve helps; skip extra containers when you need direct, continuous feed.

The tradeoff: One source recipe run makes 1 and lists 8 Iron Plate at Constructor; 1 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. Count its construction cost separately from the stored stock and keep the downstream target visible so the buffer does not hide a shortage.
