  Scenario: Keep a work draft across deployment
    Given Alice has typed an unsaved work entry
    When the backend stops for deployment
    Then the open client shows a maintenance message
    And a fresh public request shows a maintenance page
    When the deployment succeeds and Alice reconnects
    Then her draft is available for review
    And it has not been automatically saved

  @WJ-037 @browser
  Scenario: Show an offline notice without committing work
    Given the device loses connectivity
    When Alice opens the app
    Then an offline notice is displayed
    And no work or habit mutation is reported as saved

  Scenario: Initialize and override the language
    Given a new user's preferred supported browser language is German

    Then the interface is German
    When the user chooses English

  @WJ-039 @browser
  Scenario: Keep theme overrides local to the device
    Given Alice's smartphone is set to dark and her desktop to system

  Scenario Outline: Export private tracking data
    Given Alice and Bob both have tracking data
    When Alice exports <period>
    Then one versioned JSON file contains only Alice's records in that period
    And referenced catalog names and effective allowances are included
    And no credentials or push secrets are included
    Examples:
      | period        |
      | September 2026|
      | the year 2026 |

  @WJ-041 @browser

  Scenario: A different account cannot recover a private draft

  @WJ-058 @browser
  Scenario: Preserve a second tab's work draft after saving the first
    Given two tabs have separate drafts for the same work entry
    When the first tab saves its changes
    And the second tab reloads and opens its draft
    Then the second tab still shows its own unsaved input
    And adopting the first tab's version requires an explicit action

  @WJ-059 @browser
  Scenario: Recover a work draft from a closed tab
    Given Alice has an unsaved work draft in a tab
    When she closes that tab and opens the same form in a new tab
    Then she can explicitly open the earlier draft from this device
    And no work is saved merely by opening the draft
