  "description": "Meta's heritage Facebook-blue corporate reading — legacy FB-blue #1877F2 (Pantone 2727 C) on white canvas, with deep Cobalt #0457cb as the pressed secondary. Optimistic-Display-class neutral grotesque rhythm with Meta-blue surfaces #f1f4f7 spotlight + #dee3e9 sunk. Atmosphere id specifically encodes the heritage corporate-blue voice (modern Meta has shifted toward Cobalt #0064e0). Distinguished from threads-mono-dark by mode + tone (corporate marketing vs Threads austerity).",
