/* ============================================================
   SPECTRUM Instruments
   Colours are sampled from the Spectrum flyer: red wordmark, orange and
   navy swooshes, indigo text. Each measured variable owns one of them:
   level = indigo, pressure = red, temperature = orange, flow = navy.
   Type is one family (Archivo) at three widths: condensed for tags and
   the giant hero word, regular for reading, wide for headlines.
