/* ---- Non-production banner (js/site.js, SITE_ENV) ------------------------- */
/* In the markup of every page that is not production (index.html, 404.html); js/site.js
   REMOVES it when SITE_ENV is "prod", so a page whose JavaScript failed shows the test
   notice rather than passing for the live site.

   It does NOT replace the edge HTTP Basic Auth gate — that gate is still on this
   distribution (infra/terraform/marketing.tf), and only the app's came down with
   #217/#218. The banner is the innermost of three layers, for whoever is past the gate:
   gate, then X-Robots-Tag noindex, then this.

   Sticky above the nav rather than scrolling away — somebody who lands halfway down from
   a shared link should still be told. Slate, not amber: this is a fact about the
   environment, not a warning about the content. */
