Detailed Description

Factory for the DecayVolume subsystem (decay region + SBT).

Builds an air container holding the Surround Background Tagger — a steel H-beam supporting structure and LAB scintillator sensor cells forming a 50 m rectangular frustum — wrapped around a central helium decay volume. The SBT geometry is defined by the constants in SBTConstants.h.

The helium is not an independent volume: it is derived from where the SBT material actually is (see SBTEnvelope.h), so that it can neither overlap the structure and sensors nor leave an unphysical margin behind.

Z: 32.92 to 83.32 m -> centre 58.12 m; placement handled by SHiPGeometry.
