This is a mechanism claim, not a mood. It can be demonstrated on screen in a few seconds, a buyer can check it, and someone comparing three similar tools can act on it. Product-led proof also survives the sceptical viewer who discounts an emotional appeal outright.

The proof type. The artefact on its own, the mechanism that produces it, a side-by-side of four recollections against one set of notes, and a timed demonstration. The claim is held constant while the evidence for it changes.

If the artefact alone carries it, the product can lead every execution and the pipeline goes static-first, which is cheaper and faster to iterate. If the mechanism is the part that convinces, motion becomes the primary format and the next drop tests how much process to show before the payoff.
