   Lost Castles  |  site.css
   Static presentation layer for the Lost Castles redesign.
   Sits on top of a self hosted Bulma 1.0.2 and re-skins every framework
   default so no recognisable Bulma surface remains.
   Naming token "kastel" and the token values below are derived from the
   project design seed.
