   Wolkenbach IT — Design Tokens
   Brand colors derived from the official brand sheet:
     Primary  = #0e6989  (deep teal-blue)
     Accent   = #4ea2c6  (lighter sky blue)
   Brand sheet background ≈ #021326 → #0a2540 (deep navy gradient).
   The "IT" in the wordmark uses the primary; "WOLKENBACH" uses
   the accent — both sit on the deep navy.
