Feature: Start cooking an optimized plan
  As a member of a household with a planned week
  I want to open an optimized cooking plan from my planning
  So that shared preparation is pooled and I cook the week efficiently

  Background:
    Given I am signed in as "Alice" "Martin"
    And my household id is 1
    And today is frozen at "2026-08-17T09:00:00.000Z"

  Scenario: The "Commencer à cuisiner" button is disabled while the week is empty
    Given the planning request returns nothing
    When I visit "/"
    Then the "Commencer à cuisiner" button should be disabled

  Scenario: Opening the plan from the planning shows the pooled prep in mise en place
    Given the planning for this week has recipes "Soupe à l'oignon" and "Tarte à l'oignon"
    And the cooking plan for "2026-08-17" pools "Hacher" of "Oignon" across both recipes
    When I visit "/"
    And I click the button "Commencer à cuisiner"
    Then the URL should include "/cuisiner"
    And I should see "Mise en place"
    And the pooled prep task should mention "Hacher" and "Oignon"
    And the pooled prep task should be flagged as shared
    And the pooled prep task should sit in the recipe section "Soupe à l'oignon, Tarte à l'oignon"

  Scenario: The stepper walks the phases one at a time
    Given the planning for this week has recipes "Soupe à l'oignon" and "Tarte à l'oignon"
    And the cooking plan for "2026-08-17" has a mise en place then a cooking step
    When I visit "/cuisiner?date=2026-08-17"
    Then the current cooking step should be "Étape 1 / 2"
    And I should not see "Faire mijoter le bouillon"
    When I go to the next cooking step
    Then the current cooking step should be "Étape 2 / 2"
    And I should see "Faire mijoter le bouillon"
    When I go to the previous cooking step
    Then the current cooking step should be "Étape 1 / 2"

  Scenario: A ticked task stays ticked while moving through the stepper
    Given the planning for this week has recipes "Soupe à l'oignon" and "Tarte à l'oignon"
    And the cooking plan for "2026-08-17" has a mise en place then a cooking step
    When I visit "/cuisiner?date=2026-08-17"
    And I tick the cooking task "Hacher"
    Then the cooking task "Hacher" should be done
    When I go to the next cooking step
    And I go to the previous cooking step
    Then the cooking task "Hacher" should be done

  Scenario: The Recettes tab lists the week's planned recipes
    Given the planning for this week has recipes "Soupe à l'oignon" and "Tarte à l'oignon"
    And the cooking plan for "2026-08-17" has a mise en place then a cooking step
    When I visit "/cuisiner?date=2026-08-17"
    And I open the "Recettes" cooking tab
    Then I should see "Soupe à l'oignon"
    And the recipe "Soupe à l'oignon" should link to "/recettes/1"
    And the recipe "Tarte à l'oignon" should link to "/recettes/2"

  Scenario: Two recipes preheat the oven to different temperatures
    Given the planning for this week has recipes "Gratin" and "Rôti"
    And the cooking plan for "2026-08-17" needs the oven at 180 °C and 210 °C
    When I visit "/cuisiner?date=2026-08-17"
    Then I should see the oven conflict note "enchaîner 180 °C puis 210 °C"
    And I should see "Préchauffer le four à 180°C"
    And I should see "Préchauffer le four à 210°C"
    And I should see the recipe sections "Gratin" and "Rôti"
