Lamp Socket Cup V1

implemented unverified

Revolved cup holding a standard lamp socket insert (E27 or GU10 preset; any explicit inner_d overrides the preset). Central cable exit through the base is profile-native; bolt-circle mounting holes seat their heads INSIDE the cup, so it screws flat onto a bracket arm tip or any plate. Mounts inverted for a hanging lamp — the geometry is orientation-free.

Built from a real example — orbit to inspect.
