/* ==========================================================================
   Companion Pathways — theme layer (on top of base.css)
   Palette (DS-2, exactly four):
     #0F1117  Void Ink   — page background, deepest surface
     #C9A96E  Warm Amber — accent, headlines, interactive hover
     #E8E2D9  Parchment  — body text, primary readable copy
     #2A2D38  Slate Dusk — card / nav surfaces, dividers, secondary bg
   Type pairing (DS-6): Fraunces (humanist serif display) + Spectral fallback
   for headlines; Public Sans is not used — body uses a distinctive grotesque.
