"""Centralized domain configuration for research agents.

This module defines research domains and their associated prompts,
allowing the agent to operate in domain-agnostic or domain-specific modes.

Usage:

    # Get default config
    config = get_domain_config()

    # Get specific domain
    config = get_domain_config(ResearchDomain.SEXUAL_HEALTH)

    # Use in prompts
    system_prompt = config.judge_system_prompt
