FIRST-LOAD
Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the fx fee register: your exchange transaction | local amount spent | converted charge billed stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Focusing only on advertised zero-fee claims while paying a padded exchange rate. After: the fx fee register shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Format my non-sensitive notes for a fx fee register. Return plain rows only: exchange transaction | local amount spent | converted charge billed. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
