/**
 * Block O3 — visual coherence tests.
 *
 * Asserts the design-token + component contract introduced by the O3
 * pass.
 *
 * 2026-06-10: token assertions moved from "/" to "/help" — the home
 * route now serves the self-contained Landing2030Page without the
 * master Layout CSS.
 *
 * NOTE: This test runs WITHOUT mock pollution — no `mock.module()`,
 * no shared global state, no DB. It only hits in-process HTTP routes
 * via `app.request()` and renders the canonical components directly
 * to strings via hono/jsx's built-in stringifier.
