  * QA overrides on their own DataStore file, so resetting them never touches user settings and they
  * stay out of backup/export.
  *
  * The store is **not** a Koin binding: a second unqualified `DataStore<Preferences>` would collide
  * with the app's own one in `sharedPlatformModule` and both layers would end up reading the same
  * file. Each platform's `createDebugConfigSource(...)` builds it and hands it straight to this
  * constructor.
  *
  * Values are stored under the bare key name — the file is dedicated, so there is nothing to
  * namespace against.
