/* =========================================================================
   chart.css - scoped styles for /markets/chart (the Chrysofi Chart Studio,
   the site's own candlestick chart with drawing tools). Everything is
   prefixed .cs- so nothing leaks in or out; colors come from the global
   theme tokens so light/dark/accent presets apply automatically.
   The chart engine is the self-hosted KLineChart bundle in js/vendor/
   (canvas-based: it cannot be broken by page CSS, and its own colors are
   set from JS reading the same tokens).
