/* Dashboard styling: dense trading-infrastructure console, dark by default,
   readable down to phone width. Colour is carried by tokens so the whole
   palette can be re-themed from :root.

   The lime accent (--accent-lime) is reserved for a handful of deliberate
   spots (active nav item, live indicator, positive P&L, primary CTA) — it is
   not a general-purpose interactive colour. Everyday interactive chrome
   (links, focus rings, secondary highlights) uses --accent (info blue)
   instead, so the UI doesn't read as "everything green". */
