I love seeing civic design systems treat a city's visual legacy with such clarity. The Chicago Design System lays out its foundational civic marks, from the historic star geometry down to the Big Shoulders municipal typeface. Seeing how they engineered an OpenType ligature where typing CHISTAR renders the official star glyph feels wonderfully thoughtful for everyday staff. The structure also thoughtfully accounts for department lockups like CHI311 and community partnerships across pride and national flags.
