Sulphuric Acid

Fluid routing can become the constraint even when the recipe graph has enough solids; include pipe/power and all acid consumers in the selected chain.

When it fits: Plan it when a current source recipe names acid as an input.

The tradeoff: One source recipe run makes 8 and lists 10 Sulphur Ore, 2 Chemicals, 1 Wolfram Powder at Compounder v.2; 2 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. The old pack's fluid quantities require current verification; don't treat a craft amount as a rate or a stable pipe flow.
