/*
  DIRECTION CONTRACT
  THESIS: performance marketing sold like a trusted local agency, not a hardware
  product — warmth and proof over cold minimalism, open to any business niche.
  OWN-WORLD: deep navy ground, one confident blue glow accent, glass cards with
  real offset+blur shadows, bold geometric Plus Jakarta Sans display type.
  STORY: any business owner needing active demand sees Crezco proves results
  (real anonymized cases) and structures the whole system (media + commercial),
  then acts via WhatsApp or the qualifier.
  FIRST VIEWPORT: centered bold headline over a glowing mesh ground, WhatsApp
  CTA, a floating phone mockup showing live lead notifications to the right.
  FORM: assigned direction from concept-seed (thermal-receipt/poster lineage),
  raised by user-pinned reference (dark navy glass agency site); seed 9964f00e.
  FINISH: unreviewed and undocumented is unfinished; this build ends with the
  finish review, the verdict, DESIGN.md, and every shipping raster carrying
  its provenance.
