Brand-spend decision kit

Start with reader-worksheet.md or print brand-spend-decision-worksheet.pdf.
The PDF has three pages with space for notes; it is not an interactive form.
descriptive-click-example.csv contains the guide's invented before/after example.
economic-scenarios.csv contains conditional teaching assumptions, not a lift study.
These CSV tables are static. Editing them does not recalculate another file.
No account connection, customer data, scripts or advertising changes are required.
Do not treat this kit as statistical validation, a forecast or authorization to spend.
