"""Runtime settings store.

Configuration can come from two places: environment variables (the deploy-time
|
||
|
|
defaults) and a JSON file written by the in-app Settings page. The file, when
|
||
|
|
present, wins. ``load`` returns the effective settings; ``save`` persists the
|
||
|
|
editable subset and returns the new effective settings.
