   picker interaction, so "mirror the app unit" goes stale. Fix: label options
   with both units ("5 miles (8 km)") so nothing can go stale; widget rows keep
   mirroring the live unit.
+- [ ] **Localizable.strings: normalize keys to match copy** — today 8 onboarding
+  keys diverge from their values (key = old source literal, value = tightened
+  copy, e.g. "…updated twice a day" key vs "…updated daily" value). Option to
+  rename keys so key == value everywhere. Requires sweeping every Swift
+  occurrence of the old literal (Text/NSLocalizedString) AND updating key +
+  value together in one commit + rebuild — renaming the file entry alone
+  silently reverts copy to the Swift literal at next build. Not recommended:
+  keys are invisible anchors; value edits already change copy without code
+  changes, and normalization reintroduces divergence on the next value edit.
