   The brief asks for "Minecraft + modern gaming website", and explicitly not a
   2013 fan page. The way that is resolved here: Minecraft supplies the STRUCTURE
   (slots, panels, bevels, a hotbar) while modern web supplies the SPACING, TYPE
   and MOTION. Pixel styling is confined to borders and interactive chrome. Body
   text is a normal readable sans, never a pixel font - a pixel font at paragraph
   size is the single thing that makes a Minecraft site look amateur.

   Colour comes from the game's own materials rather than the purple/blue gradient
   the brief rules out: grass green, deep stone, emerald, redstone, amethyst,
   netherite. All greens are checked to hold contrast on the dark stone base.
