Transform the uploaded golden retriever photo into a classical royal oil painting. Preserve the dog’s exact face, eye shape, nose, smile, ear position, body pose and golden fur color so the pet remains immediately recognizable. Replace the plain room with deep emerald drapery and painterly studio lighting; add a tasteful small velvet cape with restrained gold trim. Use rich old-master brushwork and canvas texture while keeping anatomical accuracy. No crown, text, human hands or exaggerated costume.
