html.html.twig file, but there are two separate .js sources depending on which environment I'm on (production, and non-production). I believe Acquia Cloud (which we use) provides such variables, but they are for PHP.
I'm still relatively new to Drupal 8, so I might be missing something obvious with this, but...is there a way to use Acquia Cloud's environment variables in a Twig template?
(EDIT) I forgot to mention that I tried accessing the environment variables from a few preprocess hook functions, e.g.
themename_preprocess_page(), but they are apparently not set at all.
