ZDDC/tests/nav.spec.js

// Tests for shared/nav.js — the lateral project-stage strip.
//
// The strip's render decision depends on location.protocol and
// location.pathname. file:// won't render at all (online-only). To
// exercise online behavior we spin up a tiny in-process HTTP server
// for this spec so the page can be served from http://127.0.0.1:<port>
// at arbitrary paths.
