+Feature: Adding a recipe to the planning
+  As a signed-in user
+  I want to add a recipe to a planning slot even when I haven't imported it yet
+  So that browsing an external source and planning it is a single trip
+
+  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"
+    And the household request returns no household
+    And the recipe catalog contains nothing
+    And the ingredient and diet catalog is available for import
+    And the sources reference list has options
+    And the household has enabled TheMealDB
+    And browsing TheMealDB returns some items
+    And the planning request reflects whatever's been added so far
+
+  Scenario: Adds a not-yet-imported source item to a planning slot, importing it on the way
+    Given previewing TheMealDB item "9999" is available
+    And importing the previewed item will succeed and return id 99
+    And adding the imported recipe to the planning will succeed
+    When I visit "/"
+    And I click the add button for the first empty planning slot
+    And I click the button "Sources"
+    And I click the source item "Fish Pie"
+    And I click the link "Importer cette recette"
+    Then I should see "Cette recette sera automatiquement ajoutée à votre planning une fois importée."
+
+    When I choose an ingredient for the unresolved line "some mystery paste"
+    And I select the ingredient "Sel" from the picker
+    And I select unit "unité" for the first ingredient
+    And I fill in the last ingredient's quantity with "1" and unit "unité"
+    And I click the button "Importer"
+    Then the planning add request should have included recipe 99, weekDay "lundi", meal "petit-dejeuner", and portions 4
+    And the URL should be the home page
+    And the recipe "Fish Pie" should appear in the first planning slot with 4 portions

+Feature: Browsing external recipe sources
+  As a signed-in user
+  I want to browse the recipes available from my household's enabled sources
+  So that I can find new recipes to import, or jump straight to ones I already have
+
+  Background:
+    Given I am signed in as "Alice" "Martin"
+    And my household id is 1
+    And the disliked ingredients list is empty
+    And the planning request returns nothing
+
+  Scenario: Prompts to enable a source when the household hasn't enabled any
+    Given the recipe catalog contains nothing
+    And the sources reference list has options
+    And the household's enabled sources are empty
+    When I visit "/recettes"
+    And I click the button "Sources"
+    Then I should see "Aucune source n'est activée"
+
+  Scenario: Browses an enabled source, distinguishing already-imported items from new ones
+    Given the recipe catalog contains nothing
+    And the sources reference list has options
+    And the household has enabled TheMealDB
+    And browsing TheMealDB returns some items
+    And recipe 2's detail is available
+    When I visit "/recettes"
+    And I click the button "Sources"
+    Then I should see the source item "Chicken Handi"
+    And I should see the source item "Fish Pie"
+    And the source item "Chicken Handi" should be marked as already imported
+
+    When I click the source item "Chicken Handi"
+    Then the URL should include "/recettes/2"
+    And the recipe detail panel heading should be "Omelette"
+
+  Scenario: Previews a not-yet-imported item, highlighting its detected techniques
+    Given the recipe catalog contains nothing
+    And the sources reference list has options
+    And the household has enabled TheMealDB
+    And browsing TheMealDB returns some items
+    And previewing TheMealDB item "9999" is available
+    When I visit "/recettes"
+    And I click the button "Sources"
+    And I click the source item "Fish Pie"
+    Then the recipe detail panel heading should be "Fish Pie"
+    And I should see the highlighted technique "Cuire"
+
+  Scenario: Reviews an import, resolving an unrecognized ingredient before confirming
+    Given the recipe catalog contains nothing
+    And the sources reference list has options
+    And the household has enabled TheMealDB
+    And browsing TheMealDB returns some items
+    And previewing TheMealDB item "9999" is available
+    And the ingredient and diet catalog is available for import
+    And importing the previewed item will succeed and return id 99
+    When I visit "/recettes"
+    And I click the button "Sources"
+    And I click the source item "Fish Pie"
+    And I click the link "Importer cette recette"
+    Then the "recipe-name" field should have the value "Fish Pie"
+    And the recipe should include the ingredient "Oignon"
+
+    When I choose an ingredient for the unresolved line "some mystery paste"
+    And I select the ingredient "Sel" from the picker
+    Then the unresolved ingredients section should no longer be shown
+    And there should be 2 ingredient rows
+
+    When I select unit "unité" for the first ingredient
+    And I fill in the last ingredient's quantity with "1" and unit "unité"
+    Then the "Importer" button should not be disabled
+    When I click the button "Importer"
