Pentagram Info-Architecture (信息建筑·红) — rational Swiss-grid data decks adapted from the ppt-pentagram showcase of 花叔 (alchaincyf)'s huashu-design. Black-and-white restraint on a 1920×1080 canvas, Helvetica Neue hierarchy, one red (#E63946), 64px black chrome bars, 5%-opacity grid hairlines, giant 900-weight numerals anchoring red/dark/grey comparison bar charts. Use when the user wants a data report, benchmark deck, annual report, KPI review, 数据报告, 基准对比, or a Swiss-grid / Pentagram-style presentation.

From the source SKILL.md

Produce a single-file, Swiss-grid data deck. You are an information architect working in HTML: every page is a measured grid, every number has a coordinate, and red appears exactly where the eye must land. 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.
