/**
 * Unit tests for the Nessa landing page metadata.
 *
 * Mirrors the `page-head-meta.ts` testability pattern — `nessa/meta.ts` is a
 * pure module (no solid-js / @solidjs/router / @solidjs/meta imports) so
 * `bun:test` can resolve it. Asserts the metadata matches Nessa's actual
 * product positioning as a privacy-first fitness app
 * (per `~/code/Nessa/plans/2026-03-16-marketing-strategy-launch-positioning.md`).
