Fantasy 'In Cats We Trust' collectible $100 banknote design

Create an ultra-realistic, museum-quality collectible fantasy United States $100 banknote inspired by classic American currency design while remaining clearly fictional. Display both the front and back of the note stacked vertically on a clean, light neutral background with soft studio lighting and subtle shadows. Front Side: Feature a beautifully detailed gray-and-white domestic cat replacing the traditional portrait inside an ornate engraved oval frame. The cat has expressive amber eyes, soft realistic fur, and a calm, dignified expression. Surround the portrait with intricate guilloche patterns, micro-line engraving, ornamental borders, anti-counterfeit textures, decorative paw-print motifs, a blue vertical security ribbon, green Treasury-style seals, realistic serial numbers, denomination markings, and premium engraved typography. Include playful fictional details such as the cat's name engraved beneath the portrait. Maintain the elegant appearance of a premium engraved banknote while avoiding an exact replica of real currency. Back Side: Illustrate a breathtaking pastoral countryside at golden hour. A gray-and-white cat sits proudly on the porch of a charming farmhouse, overlooking rolling green hills, a red barn, windmill, white picket fence, wildflowers, large shade tree, and distant mountains beneath a glowing sunset sky. Blend the landscape seamlessly into an engraved currency-style frame with intricate borders and decorative flourishes. Include whimsical fictional text such as "IN CATS WE TRUST", subtle paw-print accents, and large decorative 100 denomination numerals integrated into the design. Style and Quality: Hyper-realistic engraved currency illustration. Ultra-fine linework and guilloche patterns. Premium anti-counterfeit inspired detailing. Soft natural color palette with muted greens, blues, and warm gold tones. Photorealistic cat fur and highly detailed countryside. Crisp typography and ornamental engraving. Luxury collectible banknote aesthetic. Extremely high detail, 8K resolution, sharp focus, professional studio presentation. Symmetrical composition with the front note on top and the back note below.
