Titanium Rod

It represents a conversion step between raw titanium and advanced construction; surface it as a chain target, not a raw resource.

When it fits: Add it when a selected building or product explicitly needs rods.

The tradeoff: One source recipe run makes 1 and lists 1 Titanium Bar at Fabricator; 2 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. The rod recipe draws from a shared titanium stream; mining, smelting and transport remain separate constraints.
