• The notification target is a picker too now — choose the phone or tablet from a list
  instead of typing a service name. A text field stays alongside it and takes precedence.
• Both are needed, and the reason is worth knowing: the service name is derived from the
  device name, so two devices called the same thing cannot be told apart (on the
  reference system there are two called "iPhone"; one of them is really
  notify.mobile_app_iphone_2). Renaming a device after registration breaks the derivation
  as well, and a notification group cannot be picked as a device at all. So the picker
  is the convenience, the field is the guarantee.
• A condition now refuses to run when neither is set, instead of failing inside the action
  with an unhelpful error.
• ⚠️ Updating an already-imported blueprint needs a re-import. Pasting the URL again
  does not replace the installed copy — Home Assistant keeps the old one. Use
  Settings → Automations & scenes → Blueprints → ⋮ → Re-import blueprint.
