/* ============================================================
   Meridian Markets — design system

   Colour discipline, which is the single most important decision
   in a trading UI: GREEN AND RED ARE RESERVED FOR PRICE DIRECTION
   ONLY. Traders read colour before they read numbers, so the brand
   accent is amber — it can never be mistaken for a gain or a loss.

   Type: Newsreader (serif) for marketing headlines, to read as an
   established institution. Inter Tight for dense UI. IBM Plex Mono
   for every numeral, so columns align and digits don't dance.
