   One language.
   A single design system for every page: tokens, type, shell, components,
   diagrams, and slides. No page owns its own dialect.
   Exception: depicted product UI (chat mock, terminal mock, prompt
   bubble) keeps a few literal values because it portrays software,
   not the site. Everything editorial shares the tokens below.
