/* ==========================================================================
   TrackImpact design system
   --------------------------------------------------------------------------
   One shared stylesheet for every page (linked from base.html). The visual
   identity is "editorial intelligence": a scholarly serif (Source Serif 4)
   for display + a disciplined sans (Inter) for UI and data, set on warm
   paper with an ink-navy accent. Self-hosted variable fonts — no CDN.

   Page templates keep their own <style> blocks for layout, but colors flow
   from these tokens (var(--accent) etc.), so retheming happens here.
