Previews notification rendering through the production library pipeline.
The canonical preview path is the Chimeway.preview_rendering/3 API function.
This task is a data-only wrapper for CLI convenience.
For advanced executable Elixir preview experimentation, use mix run -e or iex -S mix
rather than passing executable inputs to this task.
Usage:
mix preview.rendering --notifier MyApp.Notifiers.CommentCreated \
--params-json '{"id": 1}' \
--recipient-json '{"id": "recipient-1"}' \
--channel email
