/* ============================================================================
   Fechamento IA — Gênesis IA
   DESIGN DIRECTION: "Tactical Playbook" (Hard Rule #16 — NEW, unique to this tool)
   ── Direction: a strategist's/coach's tactical board — the sales conversation as
      a set of designed "plays". Chalkboard, chalk routes, whistle & clipboard.
   ── Palette / type / layout: deep chalkboard-slate canvas (#14211c) + chalk-cream
      ink (#ece6d6); tactical safety-orange (#ff7a3d) primary + signal-teal (#37d9b0)
      secondary; condensed athletic display UPPER for labels + clean grotesk body +
      mono micro-labels; chalk-dust grain + hairline tactical grid; roomy play cards.
   ── Signature element: every scenario is a "PLAY" card — a chalk play-diagram header
      (dotted route between circled nodes) above the realistic WhatsApp chat-bubble
      execution. NOTE: app chrome = Tactical Playbook, but the WhatsApp preview itself
      keeps an ACCURATE WhatsApp look (green outgoing / light incoming) so the artifact
      is realistic + export-safe (chrome-vs-artifact discipline, like anuncios/sequencia).
