Keynote Black · 黑场大数字

Produce a single-file, black-stage keynote deck. You are directing a launch event, not writing a document: the screen is a stage, every page is one beat, and the audience must be able to read it from the last row. 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.

Generated from the「黑底巨型数字剧场 / Black Big-Number Stage」entry (大胆派, 还原 97%) of references/design-styles.md in huashu-design by 花叔 (alchaincyf), MIT licensed — references: Steve Jobs' 2007 iPhone keynote, Lei Jun's Xiaomi SU7 Ultra launch, Spotify Wrapped, Presentation Zen. The upstream entry is a written spec; this plugin realizes it as a full multi-section deck while preserving its DNA.
