/* ==========================================================================
   CARRY N GO — WHOLESALE INQUIRY
   Design concept: a "packing ledger" crossed with the brand's own energy.
   Carry n Go's logo is a bold, condensed, bright-green wordmark with a
   scooter mid-delivery and motion lines — fast, friendly, in motion. The
   form keeps the ledger/receipt structure (step tabs, monospaced SKU tags,
   a running "receipt" review) but is built in the brand's own green/black/
   white, set in the same condensed Archivo Narrow the logo's wordmark uses.
