/*
===============================================
FALCON TRADING - STYLE 9
Modern Purple/Coral Theme
===============================================

UI/UX DESIGN DECISIONS:
-----------------------
1. COLOR PALETTE: Purple/Violet primary with warm coral accent
   - Creates premium, trustworthy feel
   - High contrast for WCAG AA compliance

2. TYPOGRAPHY: DM Serif Display + Inter
   - Serif headlines = elegance & tradition
   - Sans-serif body = readability & modernity

3. SPACING: 8px base unit system
   - Consistent rhythm throughout design
   - Generous whitespace for breathing room

4. MOBILE-FIRST: All styles start mobile
   - Progressive enhancement for larger screens
   - Optimized for touch interactions
