/* ============================================================================
   sma-terminal.css — Smart Money API data-page terminal kit (tk-*)
   ----------------------------------------------------------------------------
   Shared component layer for the DATA & CHART pages (screener, options, ETF,
   onchain, mood, historical, heatmap, news, swaps, performance).
   Design goals, in priority order:
     1. Most decision-relevant info above the fold — compact command header,
        KPI ribbon, hero visualization.
     2. Purposeful density — hairline separators instead of padding walls.
     3. Readability — tabular/mono numerals, right-aligned figures, ≥4.5:1.
     4. Progressive disclosure — educational prose folds into .tk-guide.
   Every class is namespaced `tk-` so nothing leaks into non-adopting pages.
   Tokens bridge to theme-aura.css / theme.js vars with dark fallbacks.
