Runs a structured synthetic-persona critique through Groq using the configured model

Runs a structured synthetic-persona critique through Groq using the configured model. The persona is treated as a hypothesis, never as a factual claim about every member of a demographic group; the response must state its assumptions and avoid sensitive-trait stereotyping. Input leaves this server for Groq and is not stored by HALOWERK. This is qualitative simulation, not user research, survey evidence or proof of conversion impact.
