Replace the text of a node of a group, as typing it in the app would: a generator's prompt, a text node's body, or a story element's stage body (the Story element node of a story element group, for that group's stage). @# tokens are checked (every token must cite something in the project); on a generator the reference edges follow the tokens, so a token you drop disconnects that input and a token you add connects it. Defaults to the group's default target (defaultNodeId in get_group: a shot's panel, the starred generator of a production group or the art direction, a story element's Story element node); nodeId picks another. Read the current text and its references with get_group first. The shot panel's prompt is managed by the app: a prompt you set there is kept as written (it no longer follows the shot's action, framing and camera) until you call again with restoreDefault: true. Story element referenceHandles (@ref_…) are turned into live references. No images are generated and no credits are spent.
