Emulates the reasoning habits of Claude Fable 5 — plan before executing, self-refutation, iterative verification until it passes, lead with the result, and scope discipline. Use when the user says "fable mode", "modo fable", "razona como fable", "reason like fable", or on any non-trivial coding, debugging, writing, analysis, or decision task where reasoning quality matters more than speed.
