/* ============================================================
   Colombia Amphibian Explorer  —  Glass Frog Palette
   Extracted from Centrolenidae glass frog ventral photograph:

   Near-black    #020A04  — photo void background
   Teal body     #4ABFA0  — translucent glowing skin
   Vivid teal    #6CDCB8  — iridescent highlight
   Yellow-gold   #C8A820  — toe pad pigment
   Coral-salmon  #C87060  — visible organs through skin
   Blood red     #CC2020  — artery
   Pale belly    rgba(160,230,210,0.15) — near-invisible skin

   Design rule: everything is dark glass. Light comes from WITHIN,
   like bioluminescence — teal glows on near-black surfaces.
   The basemap is the only bright thing; UI floats above it.
