/*
 * Zanshin -- chrome modelled on Sierra Chart: flat grey control bar, black
 * chart windows with thin title bars, chartbook tabs along the bottom, small
 * type everywhere and monospace for anything that lines up in a column.
 *
 * Colour jobs (validated for CVD on #000, see README):
 *   --pos   long gamma / bullish / call wall
 *   --neg   short gamma / bearish / put wall
 *   --flip  the zero-gamma level, the one line that changes the regime
 * Everything else is neutral ink and carries a text label.
