/* AZ Design System — header chrome.
   Source of truth: the DS export's templates/website/Chrome.jsx and the
   readme "Transparency & blur" rule: the sticky header is the one place
   the system uses a semi-opaque white with a subtle backdrop blur. One
   76px row — logo mark + tracked wordmark left, nav right — closed by a
   full-width 1px hairline. Overrides az-site.css; loaded after it. */
