Marionette applications

For application work, locate marionette/package.json with Node's require.resolve from the application workspace and read its version. For rendering, observation or persistence changes, check the configured renderer or data provider. For framework changes, follow repository guidance.

Choose one task or exact API section below directly from the installed package. Documentation paths are relative to that package, not this skill. Follow additional references when the task needs them. If docs are absent, obtain the exact release or known source revision; do not substitute current website contracts.
