/* ============================================================================
   Maro for TOEFL — sub-brand identity.
   Family link to parent Maro (cerulean) but its own warmer voice for the ESL /
   high-stakes audience. Loaded AFTER /css/maro.css (reuses .btn + the ink-blot
   mascot; overrides type, color, and defines the page + question components).

   Type (contrast axis, none on the reflex-reject list):
     display = Bricolage Grotesque · body = Literata (reading serif) · labels = Geist Mono
   Color: cerulean kept as the credibility anchor; deep terracotta carries warmth.
   Warmth lives in accent + type + warm panels — NOT a cream body (clean light bg
   for reading legibility).
