Catalogue/PIS identity is recorded separately from technical values. No coverage, dilution, consumption, drying time, pack size or warranty number is inferred merely from a product name or family listing.
Use dedicated pages for products, brands, services, local information and technical guidance. Manufacturer-specific claims remain source-gated; customer reviews are treated as experience evidence rather than technical proof.
