/**
 * Video CRUD flow scenarios: settings menu, edit modal, delete modal.
 *
 * Scenarios covered:
 * - SCN-crud-settings-menu: Video card owned by logged-in user shows settings gear
 * - SCN-crud-settings-actions: Settings menu contains edit and delete actions
 * - SCN-crud-edit-open: Clicking edit action opens the edit modal
 * - SCN-crud-edit-form: Edit modal contains the expected form fields
 * - SCN-crud-edit-close: Edit modal can be closed without submitting
 * - SCN-crud-delete-open: Clicking delete action opens the delete confirmation modal
 * - SCN-crud-delete-elements: Delete modal has confirm and cancel buttons
 * - SCN-crud-delete-cancel: Cancelling delete closes the modal without removing the video
