The one theatrical object is the hero terminal, which types a real ship → promote → rollback session and wears the same dark clothes in both color schemes. The system is genuinely two-scheme: prefers-color-scheme drives a full token swap declared as CSS custom properties on :root. The build is dependency-free by rule — no build step, no external requests, self-hosted variable fonts only, vanilla JS — so the token layer is the stylesheet; there is no second source of truth.",
