   Everything on this box — hub homepage

   Visual language is borrowed from Minecraft's inventory GUI: hard 2px bevels,
   zero border-radius, stone panels. That is not decoration — the machine's
   biggest tenant is a Minecraft server and the third app is an inventory, so
   the slot is the honest through-line between all three tenants.

   No build step, no webfonts, no dependencies. Plain CSS, served as-is.
