/* ==========================================================================
   Subcurrent: "The Dive" theme
   --------------------------------------------------------------------------
   Concept: price is the calm surface; positioning is the current underneath.
   The page is a dive: it gets deeper (darker) as you scroll, a depth gauge
   runs along the side, and a live WebGL ocean moves in the background.

   Colours live in :root. One font (Sora). Cyan is the brand colour, taken
   from the logo. Green / red are only used inside charts.
