   Boogaloo Bias site styles

   Palette is sampled from the artwork itself:
     void   #040807  the hero video's background (so the video edge disappears)
     signal #57D5FF  the logo and detection-box cyan
     match  #FF00E3  the recognition GUI's high-confidence box (used only for
                     the "target over the drop zone" state)
   Type:
     Big Shoulders  headlines (civic/municipal signage voice)
     Instrument Sans  reading text
     Hack  the recognition system's own on-screen font, used only where the
           system "speaks" (the scan interface)
   The one ornament is the detection bracket from the logo and the GUI.
