  FishBidness — chart paper & ledger stamp system.
  Ink and olive pulled directly from the logo's own wordmark and fin
  color (sampled, not invented). Chart-paper background and ledger/tag
  structure stay independent of that — built to read on a phone at a
  dock in bright sun, not to look like a SaaS landing page.
