   Xentory — Design System  ·  "Painel de operações"
   A página como instrumento de uma agência de performance: anti-hype = mostrar
   os números. Três vozes tipográficas:
     · Space Grotesk (display)  → manchetes
     · Newsreader (serifa)      → leitura / corpo (voz de analista)
     · JetBrains Mono (mono)    → dados, rótulos, numeração, "voz do sistema"
   Paleta roxo→magenta→ciano mantida, mas o gradiente é ACENTO único (linha de
   topo do readout, régua do hero, anel de foco) — nunca glow de hero nem texto.
   Mobile-first. Sem frameworks. Respeita prefers-reduced-motion.
