/* Shared chrome across all demo apps.
   Sits above each demo's own header and links back into the main site.

   The demos do not share one palette: the forecasting dashboard is light and reuses
   the marketing colours, while the recommender and job search apps are dark. So this
   bar wears the *site's* brand gradient rather than any individual demo's theme —
   it belongs to the website, and it reads as chrome against both backgrounds. */
