sumMaterials(...lists): EngineeringMaterial[]

Defined in: src/ships/engineering.ts:493

Combine several material lists into one, summing the counts of any material that appears in more than one list (matched by symbol, case-insensitively). Use it to fold a blueprint's cost together with an experimental effect's — the two data modules stay decoupled, so pass in whichever lists you have:

...readonly readonly EngineeringMaterial[][]

The material lists to merge; each may be empty.

EngineeringMaterial[]

One entry per distinct material, in first-seen order, with summed counts.
