+- [ ] **Price-drop alerts: threshold control + Check now** — keep the current

+  for favourite price-drop alerts instead of a fetch-frequency slider. Scope:
+  `Minimum change` picker (e.g. 0.5p / 1.0p / 2.0p), plus a `Check now`
+  action in the Alerts tab that forces a fetch and immediately re-evaluates the
+  cheapest-favourite alert. Copy should set expectation honestly: standard
+  mode checks when FuelBoard refreshes prices (up to twice daily).
+- [ ] **Price-drop alerts: optional frequent-check mode** — if the app ever
+  relaxes the current "twice daily max" data policy, expose this as a clearly
+  separate mode rather than a freeform frequency slider. Example framing:
+  `Standard` (current behaviour) vs `Frequent` (best-effort extra checks),
+  with conservative caps (e.g. every 4–6 h, not hourly) and copy that does not
+  promise exact timing under iOS background scheduling.

   app-group store; watch target would need to be added to the project).
