/* ============================================================
   ORHEN — DESIGN SYSTEM (RV01)
   Fonte única de verdade para todas as páginas.
   Tema dark permanente — obsidian/graphite · acento cobre metálico
   Tipografia: Manrope (títulos) · Public Sans (corpo) · JetBrains Mono (técnico)

   Nota de migração: os NOMES dos tokens (--green-700, --gold-500,
   --warm-900 etc.) e das classes de componente foram mantidos para não
   exigir reescrever cada regra do zero — só os VALORES mudaram para a
   nova paleta. --accent-on-light e --gold-800 (que existiam para
   garantir contraste do dourado sobre fundo branco) hoje apontam para
   o mesmo cobre, já que não existe mais fundo claro no site.
