/* ============================================================================
   CONCEPT 1 · "THE INSTITUTE"
   ----------------------------------------------------------------------------
   Architecture, not palette, is what separates this from the other two:

     · An announcement bar carries live campaigns above everything else.
     · The homepage hero is a typographic statement with no image and no card.
     · Immediately below it, a TWO-PATH FORK: study with us, or bring us to you.
       Every visitor is one of those two people, so the page asks straight away.
     · Content sits on full-bleed photographic bands and hairline-divided lists.
       There are no card grids anywhere in this concept, on purpose.
     · Display type is Cormorant Garamond at weight 300, set very large.
