/* ==========================================================================
   Dispatch — "Signal Board" design tokens
   A cool blue-black instrument-panel dashboard, not a warm newspaper wire board (see the previous
   design's header comment — this file replaces it). Per-vertical accent color layered on top of
   shared light/dark tokens: crypto teal (flagship default), stocks blue, forex violet,
   fundamentals amber. Flat panels with a crosshair-tick corner mark instead of rounded cards —
   see plans/... this session's redesign plan for the full design rationale.

/* ==========================================================================
   Customer portal compatibility (views/*.ejs, views/partials/*.ejs)
   The portal (login/signup/dashboard) shares this stylesheet but wasn't part of this redesign
   pass — out of scope this session (see the redesign plan). These keep it fully functional and
   on-brand against the new Signal Board tokens, rather than left broken by the token/class
   rename above. header.ejs was updated directly to the new masthead markup; everything else
   below is a compatibility layer, not a second design system.
