/**
 * /playground — the Playground, the catalog product the console serves: every
 * model in every mode, with each run's tokens and cost, then the same request
 * from code. Where to start lives on /learn.
 *
 * NO TAILWIND. The sections under the hero are
 * `components/marketing/band`'s `Band` and `Head`; the type and the controls are
 * @hanzo/ui's marketing components (`ChromeText` for the heading and its badge,
 * `Title`, `Lede`, `Action`, `More`, `Leaf`); the card grids are
 * `@hanzo/ui/grid`'s `Grid`.
 *
 * Every ink, edge and ground is a semantic token of @hanzo/design (`--card`,
 * `--border`, `--muted-foreground`), so both themes draw from one statement.
 * `e2e/gates/playground.spec.ts` measures the page at every width in both.
