Translates an existing manual test step (table row, prose bullet, TestRail/Qase exported step) into a declarative Gherkin Given/When/Then step phrased in business language - strips UI mechanics ("clicks the button", "types in the field"), elevates the user intent ("signs in", "adds the product"), and aligns vocabulary with the project's existing step library. The input is an already-written manual step - not a user story and not an acceptance-criteria list. Use when a team is migrating manual test scripts to BDD, or when a manual tester is handing a script off to an automation engineer.
