/* ============================================================
   AISMITH — THE SETTING-OUT SYSTEM
   Visual concept: the site is a structural setting-out grid.
   Fragmented operational inputs are shown being reorganised
   into structured outputs — transformation as the recurring
   visual principle. Neo-grotesk led (Archivo, width axis),
   cool concrete field, graphite structure, one volt accent
   used as a surveyor's mark. Mono lives ONLY inside system
   panels (interfaces, data), never as page decoration.
