/* tech-ai / api-reference
   The project documented as its own API, three columns like the reference docs of a
   payments company: a light navigation column (the brand, a working endpoint filter,
   every section as an endpoint with a method badge), the documentation in the middle,
   and a dark code column down the whole right side where every endpoint shows its
   response: JSON built from the brief, every value a brief field verbatim (the numbers
   raw, the dates as written). The introduction documents "the token object"; the hero
   art is served as the token's image. Sections render as docs: prose, attribute lists,
   numbered steps, a dated list, an errors-style Q&A, the contract as a copyable value. */
