/* ============================================
   Página de Vendas IA — Design Direction: BLUEPRINT DRAFTING

   Brief: An architect's drafting table for sales pages. Deep navy canvas
   overlaid with a faint cyan drafting grid and hairline rules; mono technical
   annotations label every field like a spec sheet; the motif is "drafting a
   page" — measured, precise, engineered. Cyan ink on navy, amber for measures.
