   The ASIC Network: "signal" theme
   Same bones as the Stone Arch Silicon site (the founding chapter), its
   own look: blue-black night and cool whites, Archivo (semi-expanded for
   display) with IBM Plex Mono, rounded capsules and cards, blueprint
   grids, live numbers, and a globe film of the real network in the hero.
   Each section picks a theme (dark / light / paper) that sets the
   colour variables below; components only ever use the variables.
