⚠️ CRITICAL PRINCIPLES — Read Before Populating Any Template

Environment — Office JS vs Python:

• If running inside Excel (Office Add-in / Office JS): Use Office JS directly. Write formulas via range.formulas = [["=D14*(1+Assumptions!$B$5)"]] — never range.values for derived cells. No separate recalc; Excel computes natively. Use context.workbook.worksheets.getItem(...) to navigate tabs.
• If generating a standalone .xlsx file: Use Python/openpyxl. Write ws["D15"] = "=D14*(1+Assumptions!$B$5)", then run recalc.py before delivery.
• Office JS merged cell pitfall: Do NOT call .merge() then set .values on the merged range — throws InvalidArgument because the range still reports its pre-merge dimensions. Instead write value to top-left cell alone, then merge + format the full range: ws.getRange("A1").values = [["INCOME STATEMENT"]]; const h = ws.getRange("A1:G1"); h.merge(); h.format.fill.color = "#1F4E79";
