+- Preferences over floret-kit's new `core-prefs`: `SettingsPrefs` holds the

+  always following the system — and an unrelated preference write no longer

+- floret-kit's `core-di` supplies the `@IoDispatcher` the preference store runs
+  on, so Clockula no longer declares its own dispatcher qualifier.

+  ✅ floret-kit 0.4.0. `core-prefs` (56 kit tests) gives the family a typed
+  `Pref<T>`/`PrefStore` over DataStore; reads degrade to the default instead of
+  throwing, and `flow()` is distinct-until-changed. The appearance key names are

+  a follow-up in the kit's roadmap, not here — needs no data migration.
+  `core-di` carries `hilt-compiler` itself, since an `@InstallIn` module only
+  reaches a consumer's component if its own library was processed; Clockula's
+  `assembleDebug` is the integration test for that binding. Clockula's theme now
+  reads the stored preference, with the DataStore built on a corruption handler
+  so an unreadable prefs file cannot brick startup.
