     Primary Forest Green  #283627
     Evergreen             #364433
     Sage                  #556254
     Ivory                 #E7E2D7
     Antique Gold          #C2A25A
     Bronze                #8B6B34

   Green is the dominant corporate colour; gold is reserved for
   premium accents (guide §4). Layout follows §6: generous white
   space, strong alignment, minimal ornamentation.

   The one structural idea is drawn from the emblem itself — its
   vertical columns become the page's ruled grid, its waves the
   line beneath the hero.
