I like how clearly Siili Solutions walks through its visual elements. The navigation lays out four clear areas, running from Make It Real into Visual Identity, Tone Of Voice, and Downloads. In the visual identity chapter, I noticed how they derive the hedgehog symbol variants from Fibonacci numbers, specifying forms with five, eight, and twenty-one spikes alongside minimum print sizes. They also include specific guidance for AI-generated visuals right alongside photography and illustrations, connecting their narrative directly into graphic execution.
