[Purpose]
Create a funny, affectionate, photorealistic pet portrait for a social feed: exactly one pet peeking sideways around one vertical opening. Default aspect ratio is 4:5; a selected output ratio takes priority. Fill the entire canvas with the scene, without borders, panels or mockups.
[Photo rule]
PHOTO = "【写真】" is attachment context, never printed text. When a pet photo is attached, use that individual as the identity reference: preserve species, age, coat length and pigment, asymmetric markings on their correct anatomical sides, eye color, ear shape, muzzle length and nose markings. Change the location and pose, not the pet's identity. Preserve those features through the pose change; do not simply paste the source photo into a doorway. With no photo, finish using one original fictional cream-and-brown small dog, never ask for a photo. Ignore people, collars with lettering and the original background.
[Opening]
OPENING = "【扉】". Interpret wood door, refrigerator and curtain in the user's language. Blank or unrecognized opening defaults to wood door. Wood: a partly open plain honey-colored wooden door with visible grain and a simple unbranded round handle. Refrigerator: a partly open original fictional muted-teal refrigerator with an offset oval recessed grip, rounded asymmetric trim and no recognizable commercial design; animal remains standing outside the appliance, looking around its outer door edge, never trapped inside. Curtain: a softly folded plain coral fabric curtain pulled aside, with folds that visibly behave as fabric rather than a rigid panel. Never combine the three openings.
[Composition and expression]
Place the opening edge around 40 percent of canvas width. The opening hides part of the torso while the pet leans into the larger visible side. Show the entire recognizable face, both eyes and both ear tips, with a slight sideways head tilt and an alert, comically inquisitive side glance. Keep the head about 45 percent of canvas width and around the upper-middle area, with a little upper chest visible and at most one naturally connected front paw resting beside the edge. Maintain plausible joints, eye alignment and neck anatomy; humor comes from the curious pose, not giant eyes, human teeth or a warped face. Keep the body behind the opening and the muzzle in front, with correct occlusion and contact shadows. The opening and softly defocused room continue to all canvas edges; no empty white studio field. Adapt framing to the selected ratio without clipping ears or stretching the pet.
[Finish]
Use one consistent lifelike photographic treatment with individual fur strands, detailed nose texture, natural catchlights and soft depth of field. Derive lighting from the opening: warm late-afternoon side light for wood, cool kitchen ambient light plus a restrained warm edge light for refrigerator, soft bright morning light through fabric for curtain. Vary setting and light through these choices while retaining the same photographic medium. No text, letters, numerals, labels, name tags, logos, watermarks, signatures, brand-specific products, real people, existing characters or imitation of an artist's work. Do not show the source image, a comparison panel or a collage in the finished output.
