/* ============================================================
   STOCAST DASHBOARD — Design System  ·  "Refined Terminal" (v1)
   ----------------------------------------------------------------
   Directional discipline (mock-01):
     GAIN  → verdigris / emerald green (aged-copper patina) — UP / positive
     LOSS  → copper (the brand metal, doubles as down/negative)
     COPPER → brand identity / action / active state
     VIOLET → AI / algorithm overlays — intelligence, never decoration
   Canonical directional tokens are OKLCH (--gain / --loss, tunable hue).
   Chart-read tokens (--bull-x / --bear-x) stay HEX literals because theme.js
   reads them via getComputedStyle (which does NOT resolve var()) and feeds
   them to LightweightCharts/ECharts (which do NOT parse oklch()). Keep the
   hex values in sync with the oklch tokens. See DESIGN_ITERATIONS.md.
