remembers why row 47 exists. Try editing cells, switching tabs, and the mini format bar.

In a full build we’d wire these ranges to charts on a separate sheet.
What you can hand us: napkin math, bank CSVs, last year’s P&L, or a blank
sheet and a goal. What you get back: something you can defend to a lender,
a board, or your future self — plus a short walkthrough so it isn’t magic.
