Ten A/B demos, each with the plain-language prompt that produced it and the payload it compiled to. Slots into Level 4 — Substance. The chapter teaches technique and leaves the key/bound reference to the Colour Grading guide rather than duplicating it. Also adds two sections to docs/guides/color-grading.mdx: - Animating a Grade — the nine CSS custom properties, plus driving the payload from the timeline for effects that have none. Documents that --hf-color-grading-intensity does not scale a grade at render time, and that payload-rewrite animation is effect-dependent: verified working for halftone and twoInkPrint, verified not working for crtCurvature, scanlines, chromaBleed and chromaticAberration. - Limiting a Grade to Part of the Frame — grading qualifies by value, never by screen position, so a region has to become its own layer. Includes the three layer recipes and a worked face-redaction example. Previously the support matrix said "not supported" with nowhere to go. Renders are served from the CDN; docs/images/ is gitignored. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
