A modern 16:9 tech illustration using a 60/30/10 color structure: deep midnight navy foundation (60%), structured steel-blue architectural layers (30%), and neon violet accent (10%). The composition shows a device generating a cryptographic key pair, with luminous accent pulses flowing toward a domain-bound node. A physical hardware key anchors the authentication layer, emitting a secure light signature. Background grid geometry reinforces structured intelligence. The visual communicates phishing-resistant authentication, domain binding, and hardware-backed identity verification — without any text labels.
