Felix + Ravi illustrated icon — built-in image generation

Prompt: A square, hand-painted anime game icon portrait of Felix the golden fennec and Ravi the lavender bat-feline cuddled cheek to cheek. Preserve amber/green eyes, cream/white forelocks, rust-orange/purple clothing and Ravi's small bat wings. Clear expressive faces, cozy periwinkle background, small heart, no text or UI, no sprite reuse.

The generated art master is assets/branding/illustrated-icon.png. Standard Windows and Android icon sizes are produced by src/build-illustrated-icon.js. Android themed-icon mode uses a monochrome silhouette as required by that platform mode.
