/* ==========================================================================
   The Adventure Box — brand pack theme
   --------------------------------------------------------------------------
   An optional skin over app.css, for comparing against Ink & Oak. Everything
   here is a token override plus the handful of components that only exist when
   there is brand photography to place; the layout is untouched.

   Turn it on with BRAND_THEME=adventure. When one of the two wins, fold the
   winner into app.css and delete the other.

   Colours are sampled from the pack itself, not eyeballed:
     forest     #4F624C      navy    #264151
     terracotta #93563C      cream   #F1E8DC
