+Above is one custom slider - a `golden-hour light` axis spelled out with two
+pole phrases - on a single coastal prompt at a fixed seed. Only the dial
+value changes between frames: it grades the light from cool overcast down at
+`-3`, through your untouched prompt at `0`, to full golden hour at `+6`,
+while the cliff, shoreline, and framing hold. It is one of ten sliders in
+the render audit (eight worked as desired, two after pole rewording, no
+degradation at full deflection). Results, all ten audit sheets, and a
+slider-writing cookbook - what makes a strong axis, how to fix a weak
+direction - are in the [Concept Slider guide](docs/concept-slider-v1.md).
 Try [krea-slider-v1-showcase-workflow.json](example_workflows/krea-slider-v1-showcase-workflow.json)
 for six sliders, the report, and a same-seed with-vs-without branch in one
 graph.
