/* ============================================================================
   Diabot — visual system

   Palette: deep petrol ground with amber as the single load-bearing accent,
   jade reserved strictly for "verified / grounded" states and coral for
   "ungrounded". Amber-on-petrol is warm without being decorative, and reads as
   Indian clinical publishing rather than generic SaaS. Deliberately not the
   purple-to-blue gradient that every AI product currently ships.

   Committed dark theme. This is a choice, not an omission: the product's core
   idea is a citation trail, and a dark ground lets the amber citation marks and
   jade verification states carry real signal. Every colour is painted
   explicitly so the page holds on any host background.

   Type: Newsreader (editorial serif, medical-journal adjacent) for display,
   IBM Plex Sans for body, IBM Plex Mono for citations and data. Not Inter.
