/* ============================================================================
   BLUE HERON BRIEF — styles.css
   ============================================================================
   Design system carried over from the existing Morning Brief Artifact/email
   (documented in Claude's memory as the "ARTIFACT DESIGN SYSTEM"):
     - Georgia/Times New Roman serif for headings & body copy
     - Arial for small caps / labels / captions
     - Courier New for prices and other tabular figures
     - Warm cream page background, near-black header band, amber accent
     - Category colors: Markets amber, Geopolitics red, Canada blue,
       Greece green, AI/Tech purple, Books orange, Money gold
   This file only re-implements that system with real CSS (flex/grid,
   custom properties, media queries) instead of the email's nested-table
   markup, since this is a real website, not an email client target.
