If a photo of the cat is uploaded, keep its breed and coat colors. If not, make it an adorable long-haired tabby in cream and silver.

Format: professional high-end birthday poster, 4:5 ratio.

Wall: the whole frame is a premium off-white wall with a textured luxury-paper finish. A large number "3" is cut precisely into it, with real depth and believable shadows on its inner edges.

Inside the carved number: balloons in soft lavender and silver with star patterns, a few white jasmine flowers and tiny star-shaped flowers that glow, a bouquet arranged to feel elegant but playful, accents of cosmic-themed ribbon, premium party styling.

Subject: a happy fluffy cat with big expressive eyes. It sits inside the carving in a playful way, mouth open as if it were laughing naturally. Its face, one paw and its tail break out of the number, giving a realistic 3D pop-out effect.

Lighting: warm cinematic sunlight coming from the upper left, a soft rim light with gentle sparkling highlights, photorealistic fur and details.

Rendering: ultra realistic, sharp focus, premium studio photography.

Text on the wall, set in an elegant serif, three lines: line 1 "[cat's name]"; line 2 "CHAPTER 3"; line 3 "365 MORE DAYS OF WONDER".

Look: clean minimalist layout, the feel of a luxury magazine cover, high-end art direction, realistic shadows, natural colors. Playful and whimsical, yet still luxurious.

Avoid: tree shadows, fake-looking lighting, AI artifacts.
