PHOTO NOTE: "【写真】" identifies the attached pet only; never print this note.
NAME: "【名前】"
AGE: "【年齢】"
If NAME is missing or empty, use "Haru". If AGE is missing or empty, use "2歳".
Resolve the birthday line exactly once as NAME + " " + AGE + " お誕生日おめでとう". AGE includes the user's age units; never append another unit.
MOOD: "【雰囲気】"
- パステルパーティー: Blush and sky-blue balloons, soft pastel paper garland, gentle daylight.
- 暖かなリビング: Cozy linen living room, amber afternoon light, terracotta and cream balloons.
- ミニマルスタジオ: Minimal ivory studio, sage and cream balloons, restrained props, soft studio light.
If MOOD is missing or empty, use パステルパーティー. All choices remain photorealistic birthday portraits.

Create one full-bleed photorealistic pet birthday portrait. Default portrait ratio 4:5; honor the selected size. One image only, never a collage or comparison panel. Keep the pet large and recognizable, realistic fur, eyes and anatomy. Place a small cone hat gently between the ears without hiding the face, a small pet-specific savory cake made of visible plain cooked meat and pumpkin puree, balloons and a paper garland. Never depict human confectionery cake, chocolate, grapes, raisins, flames or candles. This is a fictional photo scene, not a feeding recipe. Use original unbranded prop designs; no people, celebrities, logos, packaging, signatures or watermarks.
PHOTO RULE: If an image is attached, preserve that exact pet's face, muzzle, ear shape, eye color, fur color, individual patches and markings, body proportions and recognizable pose. Change only the surroundings and add birthday accessories. Do not replace the animal with a generic breed example, mirror markings, recolor its fur or stylize it. If no photo is attached, finish with a fictional white-and-caramel small floppy-eared dog; do not ask for a photo.
Render the resolved birthday line only, once on the garland, in large clear lettering away from edges. No extra captions, ingredient claims, choice labels or explanatory text. Check every name character and age digit against the input before finishing. Never translate, shorten, autocorrect or invent a nonempty name or age; preserve user spelling and units exactly.
