## Workflow

### Phase 1: Initialization
1.  **Check:** Does `event_costs.csv` exist?

### Phase 2: The Break-Even Analysis
For each event:
1.  **Calculate Revenue Needed:** `Total_Cost`. (To break even).
2.  **Calculate Deals Needed:** `Total_Cost / Avg_Deal_Size`.
3.  **Calculate Leads Needed:** `Deals Needed / Hist_Close_Rate`.
4.  **Calculate Capture Rate Required:** `Leads Needed / Attendees`.

### Phase 3: The Feasibility Check
*   **Safe:** Required Capture Rate < 1% (Easy).
*   **Risky:** Required Capture Rate > 5% (Very hard in a busy hall).
*   **Impossible:** Required Capture Rate > 10%.

### Phase 4: Output

2.  **Columns:** `Event`, `Cost`, `Leads_Needed_to_Break_Even`, `Risk_Level`.
3.  **Summary:** "SaaStr requires 167 leads to break even (1.6% capture). Rated: SAFE. Local Meetup requires 2 leads (2% capture). Rated: SAFE."
