"""Merge Abenteuer-Schmiede config into BMAD _config/config.yaml.

Called by: BMAD module installer (npx bmad-method install)
When:      During module installation, NOT during as-setup workflow
Purpose:   Adds default Abenteuer-Schmiede config variables to the
           central BMAD config so agents can read project settings.
Idempotent: Yes — skips if 'abenteuer-schmiede:' block already exists.

Usage:
    python merge-config.py <bmad-root-path>

Example:
    python merge-config.py /path/to/my-project

This appends the following YAML block to _config/config.yaml:

    abenteuer-schmiede:
      abenteuer_name: ""
      setting: ""
      epoche: ""
      spieleranzahl: "3-4"
      erfahrungsstufe: "Durchschnittlich (300-600 AP)"
      abenteuer_typ: "Gemischt"
      geschaetzte_dauer: "Mittel (4-6 Abende)"
      sprache: "Deutsch"

These values are populated by the as-setup workflow (skills/as-setup/SKILL.md)
when the user starts a new adventure project.
