   DESIGN TOKENS
   Color:
     --ns-void:      #05070D  (near-black background, "deep space" — the AI core lives here)
     --ns-navy:       #0B1120  (panel background)
     --ns-signal:     #00E5C7  (electric cyan — "the signal" broadcasting outward)
     --ns-pulse:      #FF6B35  (warm signal-orange — human/industry touchpoints, CTAs)
     --ns-paper:      #F5F7FA  (light surface for readable long-form sections)
     --ns-ink:        #0B1120  (text on light)
     --ns-slate:      #8B96A8  (muted text on dark)
   Type:
     Display: 'Space Grotesk' — geometric, technical, built for a headline that reads like a signal readout
     Body:    'Inter' — quiet, highly legible workhorse
     Mono:    'JetBrains Mono' — data, specs, chat transcripts, code-like credibility
   Signature element:
     The "Core Pulse" — a single glowing node at center-hero broadcasting concentric
     signal rings outward to a ring of industry icons (barber, tooth, HVAC vent, wrench,
     car). This is the one visual idea: one AI core, every industry, live and pulsing.
