/* The Terrarium — MOTD styling

   A live system readout for a contained biome, not a poster: rank is
   depth and brightness, nothing is ever enclosed in a bordered/blurred
   card. One bitmap terminal face, a near-black void, four neutral steps,
   and exactly one signal color (amber) — a real DOS/VGA text-mode
   typeface stands in for the "cracktro"/demoscene loader screens that
   share the GMod community's actual PC-underground lineage, with the
   terrarium's living atmosphere reappearing as the slow-drifting spore
   dust behind every plane of text instead of as a mint gradient.
