/* ------------------------------------------------------------------
   Noo — lab517.io/noo

   Same ground, type and rails as lab517.io: this is a page of that site,
   not a second identity. Tokens below are copied from its stylesheet
   deliberately, so the two render as one domain — both themes of them, and
   the switch behaves identically on both. Light stays the default.

   The colour rule carries over, narrowed. On lab517.io colour encodes
   service status — down, degraded, live. Nothing on this page is down or
   degraded, so only --live appears, and it means one thing: local and
   yours. Every screenshot, rule and panel is otherwise monochrome.
