Introduces a production-ready, schema-driven prompt generation engine for ComfyUI, including a new 'everyday_casual' library with 290+ atomic options. Major updates include a comprehensive README, scaling and library comparison docs, a strict LICENSE (CC BY-NC 4.0), and a refactored __init__.py with improved node structure, negative prompt support, and detailed docstrings. The engine (engine/composer.py) now enforces strict separation of concerns, supports addons, intent flags, and deterministic assembly. Documentation and changelog updated to reflect the new scalable, maintainable architecture.
