/**
 * We define SCANDIC_ENV_URL for stable environments on Netlify:
 * production, stage and test. Avoid using SCANDIC_ENV_URL locally.
 * For deployments to those branches we have SCANDIC_ENV_URL defined.
 * Otherwise we fallback to DEPLOY_PRIME_URL from Netlify built-in variables.
 * Locally we set DEPLOY_PRIME_URL
 *
 * We set NEXTAUTH_URL here because build time environment variables are not
 * available runtime in Netlify functions. This leads to use being unable to
 * login on preview deployments.
 *
 * This approach updates the .env file in the root of the repo and tells
 * Netlify to include this file in the bundled function output
 * (see netlify.toml). This way Next.js will read .env runtime and update the
 * environment accordingly making the value available at runtime.
