A stone castle perched on a narrow mountain ridge, with slate rooftops, rustic timber details, and small alpine gardens flourishing on balconies. The castle should be illustrated in high-resolution PNG format with a transparent background, using a clean, detailed digital art style. The design must be centered, visually balanced, and thematically consistent with the described setting. Emphasize architectural uniqueness, atmospheric lighting, and fantasy aesthetics. Ensure the image is full-body (entire structure visible), isolated from the background, and suitable for use in digital marketplaces like e-commerce platforms, tabletop game assets, or printable fantasy decor.
