/* =================================================================
   Birds of the Sahyadris — restyled to match the
   "Curiosities" home page and "The European Gaze" collection.
   Same type pairing (Cormorant Garamond + Spectral), same warm
   paper palette and hairline editorial grammar. Green is kept as
   the birds' signature accent (as assigned in the hub).
   Structure, class names and three-panel layout are unchanged so
   this is a drop-in replacement and app.js keeps working.
