Research direction

Begin with the Thread 7 stack and inspect Feature.swift:58, GeoJSONSourceData.swift:86, and StyleSourceManager.swift:300, then trace how GeoJSON data reaches MapboxCoreMaps in SDK 11.12.2. Reproduce the intermittent launch crash on the stated iOS and device setup; done means identifying a confirmed cause and producing a verified fix or narrowed, actionable upstream report.
