// Deploy-time configuration, empty by default (mirrors gsmol's config.js).
// A release may bake in a server key with:
//   flutter build apk --dart-define=SMOL_PRESET_SERVER=example.org \
//                      --dart-define=SMOL_PRESET_SERVER_KEY=base32key
// It only makes sense when whoever ships this app and whoever runs that
// smolmaild are the same trusted party: the value arrives with the app
// itself, which is the trusted channel SPEC.md §4 asks a pin to come from.
// This only seeds the first run — once written it is an ordinary pin,
// removable in settings like any other, and never overwrites a host the user
// (or a previous install) already pinned.
