//! The theme a user project starts with — shadcn/ui's token names, verbatim,
//! Zebflow's values. Written into a new project's `globals.css`; the same
//! bytes `theme init` adds to a project that predates them. A theme exported
//! from ui.shadcn.com or tweakcn replaces the two blocks; see
//! `docs/contracts/kinds/ui-theme` for the profile a replacement must meet
//! (complete colour values, both blocks, the three status pairs).
