"""Generate deterministic golden prompt fixtures for DevRunbook P0 playbooks.
This is a specification reference, not the production implementation. The TypeScript
composer may use a different internal design, but its canonical Markdown output for
these fixtures must remain byte-identical unless the fixture contract is versioned.
