Objectives/approach

• Load config conditionally, based on a release flag passed in at the command line. We use juxt/aero to read a static config.edn file, passing in the release flag as aero's :profile.
• Config should be exposed at runtime (in the browser / cljs) and macro-expansion time (clj). We store config in a plain map, app.env/config. Our build hook, app.build/load-env, updates this using alter-var-root!.
• Whenever config has changed, shadow-cljs must invalidate its caches so that changes are picked up immediately. We do this in app.build/load-env by putting the current environment in the shadow build state, under [:compiler-options :external-config ::env].

Why this approach?

• Reading config directly from macros breaks compiler caching - changing config will not cause changes to propagate to the build.
• :clojure-defines (ie. goog-define) are not exposed in clj, & therefore can't be used by macros. We want one single way to expose config that
