/* The Undercroft (UCFT) launch page
   Concept: an abandoned Sub-Strata transit kiosk, brought back online by the resistance.
   Palette pulled from the comics: near-black, bone, copper. Cyan belongs to the Code and
   the String only. Green appears only when the network is open.
   Shape rule: interface is sharp (2px). Physical objects (cards) have card corners. */
