   ENGIA Green LLC — construction management, Tbilisi
   Hand-written. No framework, no build step, no third-party requests.

   Palette is taken from the ENGIA Green logo (Revision B), sampled from the
   original artwork and checked for contrast:

     ink      #25404A   the logo's slate navy — text, nav bar, footer, linework
     paper    #F0F2EE   cool off-white, so the logo's white disc sits cleanly
     green    #7AAB5E   the leaf — FILLS ONLY (chart bars, tints). At 2.4:1 it
                        is too light for text.
     green-d  #3D6B2B   the leaf, darkened for text and links (5.6:1 on paper)
     pale     #A8D5DD   the blades and wave — remaining time on the programme
     hivis    #F6E46A   the sun — reserved for "now": the today line on the
                        programme and the current page in the nav. It only
                        ever means "now".
     amber    #9A6200   status only: awaiting a third party (5.1:1 on white)

   Change a value in :root and the whole site follows.
