Evidence you can follow.

Official manufacturer product pages, configuration-specific brochures and installation or cleaning manuals take priority. Retailer listings are secondary evidence and do not establish worldwide availability. Every imported field keeps its URL, check date, region and verification status. Missing information stays unknown; it is never filled from an image or guessed.

Model photos help identify equipment; article and scene images provide context. Confirm the exact configuration in the manufacturer documents. Image credits and copyright information remain available with their sources.
