Small Engine

It belongs in a hull-specific bill; engine selection should follow ship type rather than being stocked as generic industry material.

When it fits: Add it once the selected small ship recipe requires this engine.

The tradeoff: One source recipe run makes 1 and lists 8 Composite, 4 Hull Plating at Fabricator; 1 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. The craft does not include hull, cargo, power or route costs; use the full ship project for material commitment.
