Create an original flat 2D mascot concept for {{service}}, inspired by {{motif}}. Use bold geometric shapes, a distinctive compact silhouette, simple {{expression}} facial features and a palette of {{palette}}. Show one complete character with minimal internal detail and consistent outline thickness. Clean vector-like edges, solid fills and no gradients. Center the character with generous padding on a plain white background. Keep it clear at small sizes and reserve space around the silhouette for later placement in a brand layout. No text, letters, embedded logo, drop shadow, mockup or watermark.
