Aetheria.Shared.csproj compiles ServerShared with MessagePack, UniRx
core, Ink and Unity.Mathematics from source against .NET Standard 2.1
(Unity's API level) with no Unity defines; a clean build checks that the
simulation stays engine-independent. tools/AetherDb opens AetherDB.msgpack
through the game's own CultCache for file-based C# scripts; station-fit
checks every station hull can take a docking bay.
