/*
  CHRONICLE TIMELINE - VISUAL STYLES

  The colors are collected here so the entire theme can be changed without
  hunting through the rest of this file. The palette is intentionally broader
  than "black and red": bone, oxidized green, and old brass keep it nocturnal
  without making every object look identical.
