"""The Configuration tab's section list (GET /api/config/parameters, engine/pipeline/parameter_registry).
 
Two sections were both labelled "Propellants" (fluids and propellant_preset), and the legacy
chamber/nozzle blocks and the app's own staleness stamp were listed beside the live sections as
if a person should fill them in.
