Add or replace a file in a template’s bundle

Registers a new file in your organization's template library and puts it in this template's bundle under `name`. A file already in the bundle under that name is swapped out. Two request shapes: - `{ name, content }` — the text of a source file, stored for you (up to 2 MB). - `{ name, mimeType }` — for binary assets: the file is registered and the response carries `uploadUrl`; `PUT` the bytes there with a `Content-Type` exactly equal to the `mimeType` you sent. The replaced file is detached, never deleted — anything that already rendered with it keeps working. **Learn more:** [Compose](https://docs.cloudraker.com/capabilities/compose)
