Net working capital (NWC) target analysis with seasonality

Determine a net working capital (NWC) target for {target_name}.

Inputs:
- Monthly BS detail (AR, AP, inventory, other current): {monthly_bs_detail}
- Revenue/COGS monthly: {monthly_rev_cogs}
- Known seasonality or one-offs: {seasonality_oneoffs}
- Proposed NWC definition from SPA (if any): {nwc_definition}

Output:
1) NWC calculation by month and trailing average.
2) Seasonality assessment and recommended target approach (avg, normalized, peak/trough adjustments).
3) Exclusions/inclusions recommendations (cash, debt-like, unusual accruals).
4) Negotiation talking points and risks.

Make assumptions explicit and tie to SPA definition.
