Pentagram Info-Architecture.

Rational Swiss-grid data decks: black-and-white restraint, Helvetica Neue hierarchy, one red (#E63946), 64px black chrome bars, 5%-opacity grid hairlines, and 260px giant numerals anchoring red/dark/grey comparison bar charts on a fixed 1920×1080 canvas. Based on https://github.com/alchaincyf/huashu-design ppt-pentagram, expanded from a single showcase page into a full multi-section deck.
