/* ==========================================================================
   UNIT 9 · PROOF AND EARLY ACCESS
   --------------------------------------------------------------------------
   Navy → deep-teal authority field, two halves:
   • Proof: accreditation seal + statement, and a metric panel with a
     count-up "6M+" and a rising bar chart.
   • Early access: a "Founding Members" membership card (3D tilt toward the
     pointer, light sheen on entrance) layered over a warm teamwork photo,
     followed by the full offer sentence.
   Static fallback: final values shown, card flat.
