   ZIDEA, Design System
   Concept: "Signal & Instrument", a data consultancy reads
   signal from noise. The visual language borrows from test
   instruments and control panels: corner-bracket frames instead
   of boxed cards, a running signal-trace motif, mono readouts
   for data, restrained amber used only where something needs
   attention.
