   Aesthetic: laboratory instrumentation. Oscilloscope, seismograph, graph
   paper. Deliberately NOT the forex-marketing vocabulary of green candles and
   gold coins -- the product is an instrument panel, and the sales argument is
   measurement, so the surface should read as a calibrated readout.

   The signature component is .reading: every claim on this site is rendered as
   an instrument reading carrying its own measurement conditions, visibly,
   never in a footnote.
