Playground & engines

Playground holds reusable creative assets for high-quality responses: generation engines, render styles, YouTube details styles, YouTube thumbnail styles, and personas. Configure engines once, then reuse them across singles, playlists, and renders.

• Generation engines — lock models and prompting defaults for consistent quality.
• Render / thumbnail / YouTube detail styles — brand the visual and metadata layer.
• Personas — keep a stable vocal identity across singles for virtual artists.
