/* JETT portal — light Linear chrome.
   Implements design-system/jett-social-ai-manager/PRODUCT-UI-LIGHT.md.
   One hand-written file: no framework, no build step, no external request.

   ponytail: the addendum names Inter + IBM Plex Mono. We ship the system stack
   instead so the portal makes zero third-party requests and has no webfont
   FOUT. To adopt the named faces, self-host the woff2 files under
   /static/fonts/ and add @font-face here — do not add a CDN <link>. */
