You are a financial modeling expert. Using the baseline cash flow data and business assumptions provided (e.g., growth rate, margin trends, CapEx), build three 12-month cash flow scenarios: Base Case, Best Case, and Worst Case.

Each scenario should include:

1. Monthly projected cash inflows and outflows.
2. Ending cash position and liquidity buffer.
3. Key sensitivity factors (e.g., revenue growth, customer churn, cost inflation).

Present your output in a structured table format and summarize the key risks and opportunities for each case.
