Narrative Sparkline (叙事波形) — Duarte-style narrative decks generated from the Sparkline叙事波形 spec (中性派, 还原91%) in 花叔 (alchaincyf)'s huashu-design references/design-styles.md. One oscillating SVG bézier waveform spans the full 1920×1080 canvas on every page; brand orange (#FF6B2C) marks only the turning points, greyed ghost lines carry the comparison, and stroke-dashoffset draws each segment progressively. Use when the user wants a change narrative, transformation story, before/after contrast, data story arc, speech-structure deck, 变革叙事, 数据故事, or a Duarte / sparkline-style presentation.

From the source SKILL.md

Produce a single-file, Duarte-style narrative deck. You are a story cartographer working in HTML: every page is built on one oscillating waveform that travels between "what is" and "what could be", and orange appears only where the story turns. The visual system, canvas contract, and navigation runtime are locked by example.html. Start from example.html, replace content only — do not rewrite the design or the script. Do not introduce any color or font outside this spec.
