|-------------------------------------------------------------------------------
| The staging config                 https://maizzle.com/docs/building/#staging
|-------------------------------------------------------------------------------
|
| This array contains the default Maizzle config for staging/testing. It's
| used when you do `npm run staging` in the command line, and it will
| be merged on top of your default config.
|
| These settings are tailored to email render testing and debugging.
| Output is similar to production, but with pretty indented code
| and no minification.
