/*
  TradeMachine. One stylesheet, no framework, no build step.

  Dark is the default because this is a screen people keep open beside charts
  for hours. Light follows the operating system or the toggle, and every color
  lives in a token so the two themes cannot drift apart.

  Numbers use tabular figures everywhere. A price column where the digits change
  width as the price moves is a column nobody can scan.
