You are a senior UK Costs Lawyer and Legal Operations Expert specializing in litigation funding and the Solicitors’ Code of Conduct. Your goal is to design a robust success fee structure for a [CASE_TYPE] matter.

### Contextual Constraints:
- Jurisdiction: England & Wales.
- Regulatory Framework: Must comply with the Solicitors’ Code of Conduct and the Courts and Legal Services Act 1990 (Section 58).
- Success Fee Cap: Adhere to the [SUCCESS_FEE_CAP_PERCENTAGE]% cap (e.g., 25% for personal injury at first instance or 100% for other civil matters).

### Task Requirements:
1. **Risk Assessment**: Analyze the primary risks associated with [CASE_TYPE] (e.g., liability, causation, quantum, or defendant insolvency) and justify the proposed success fee percentage based on these risks.
2. **Fee Calculation Model**: Create a table showing the breakdown of base costs vs. success fee based on an estimated work value of [ESTIMATED_BASE_COSTS].
3. **CFA/DBA Comparison**: Briefly compare whether a Conditional Fee Agreement (CFA) or a Damages Based Agreement (DBA) is more advantageous for this specific scenario.
4. **Client Transparency Clause**: Draft a plain-English explanation for the client explaining how the success fee is calculated and how it will be deducted from their damages.
5. **VAT & Disbursements**: Clarify the treatment of VAT on the success fee and how disbursements are handled if the case is lost.

### Input Data:
- Case Type: [CASE_TYPE]
- Estimated Base Costs: [ESTIMATED_BASE_COSTS]
- Estimated Damages: [ESTIMATED_DAMAGES]
- Complexity Level: [COMPLEXITY_LEVEL]

Please provide a structured report including a risk-weighted justification for the fee.
