Notes
Hex values resolved from the Go Brand Book v1.0 PDF (go.dev/s/ brandbook), page 16. The dark-mode role mapping is brand-atoms' sensible inversion (Black canvas, Gopher Blue identity preserved); the Brand Book is light-first and does not enumerate a dark mode but explicitly designates Black as the "high-contrast foundation."
