Act as a Senior Customer Success Strategist and Enterprise Revenue Retention Specialist. Your objective is to design an exhaustive, multi-touch churn reduction and customer win-back framework for [company_name], which provides [product_description] to [target_audience].

Context Details:
- Current Churn Rate: [current_churn_rate]

Please construct a structured, 4-phase retention strategy containing:
1. Early Warning Indicator Matrix: Identify 5 specific behavioral and usage telemetry signals that precede churn, along with automated trigger thresholds.
2. In-App & Email Interception Playbook: Create 3 tailored mitigation workflows based on explicit churn triggers (e.g., pricing sensitivity, lack of feature adoption, platform complexity).
3. Re-Engagement Email Sequence: Draft full copy templates for a 4-part email sequence targeted at recently churned accounts, leveraging behavioral psychology, loss aversion, and [available_incentives].
4. Customer Success Team Protocol: Outline standard operating procedures (SOPs) for High-Touch CSMs to conduct exit interviews that maximize account saves.

Ensure all recommendations are actionable, hyper-specific to [target_audience], and optimized for Net Revenue Retention (NRR) and Lifetime Value (LTV) growth.
