/* ================================================================
   FinceptTerminal Design System - "Obsidian" Theme
   Extracted from: https://github.com/Fincept-Corporation/FinceptTerminal
   Source: fincept-qt/src/ui/theme/ThemeManager.cpp (THEME_OBSIDIAN)
   ================================================================

   A professional dark-mode financial terminal design system.
   Built for dense data display, long-screen-time readability,
   and institutional-grade trading UI aesthetics.

   Design principles:
   1. Near-black backgrounds with subtle layering for depth
   2. Monospace typography for data alignment
   3. Amber accent for interactive highlights (not blue/purple)
   4. Green/red semantic colors for financial data
   5. Thin, low-contrast borders - never compete with data
   6. Information density over whitespace
