Retrieves Carta Total Compensation market benchmarks (salary, equity, total cash) for a role. Output to chat or CSV. Market benchmarks are triggered by queries like: "sales benchmarks", "comp benchmarks", "market rate", "what does a [role] pay", "put benchmarks in a CSV", "get benchmarks", "get carta's market benchmarks", "show me benchmarks for [role]", "compensation ranges for [role]", "p25/p50/p75 for [role]". Do NOT use for job classification or role mapping — use carta-compensation-rolematcher for that. Do NOT use for "how is OUR company positioned vs market", "who at our company is below market", or "our internal pay bands vs benchmarks" — those are roster-level positioning, use carta-compensation-scorecard. Do NOT use for fund performance benchmarks (use carta-performance-benchmarks) or portfolio structural metrics like SAFE terms and option pool sizes (use carta-market-benchmarks).
