/* ===========================================================================
   Nelanor concept-site banner + free-mockup modal
   Self-contained, fully namespaced (nlnr-cb-*) so it never clashes with a demo's
   own styles. Injected on every page of every demo under /work/<slug>/ via:
     <link rel="stylesheet" href="/work-assets/concept-banner.css">
     <script defer src="/work-assets/concept-banner.js"></script>

   Design: dark Nelanor brand chrome. Deliberately a SOLID dark surface (not the
   near-transparent glass the main site uses over its own dark body) so it reads
   clearly over BOTH light demos (Lumen, Fern & Oak, Marisol) and dark demos
   (Forge, Zelvor, Atlas). Signature: the Nelanor gradient diamond mark.

   All rules are scoped under the widget's two root ids (#nlnr-cb-root /
   #nlnr-cb-modal-root) for high specificity — this isolates the widget from a
   demo's global element selectors (a { }, button { }, input { } …) without
   leaking any styles back out onto the demo.
