/*
  DayTrader - visual identity: an old exchange indicator board.
  Amber phosphor on near-black (the actual color of pre-LCD ticker
  displays and 80s trading terminals), not the generic acid-green
  "hacker" cliche. Numbers are monospace with tabular figures so
  columns of prices actually line up, like a real ticker tape.
  Light theme flips to ticker-tape paper cream rather than plain white.
