/* ==========================================================================
   Design Principles - Modern Minimalist Data-Dense Interface
   ==========================================================================

   VISUAL HIERARCHY & DENSITY
   - High information density with breathing room via strategic spacing
   - Subtle surface elevation (minimal shadows, border differentiation)
   - Text hierarchy through weight/size, not color jumps
   - Row grouping via background tints and border accents

   STICKY NAVIGATION
   - Header row: sticky top for column context
   - First column: sticky left for row identification
   - Combined z-index layering for intersection clarity

   COLOR STRATEGY
   - Neutral grays (98-90%) for surfaces, minimal contrast fatigue
   - Accent blue for interaction states, not decoration
   - Semantic colors (danger red) only when necessary
   - Group rows: 3-5% tint of accent or gray

   INTERACTION & FEEDBACK
   - Hover: subtle background shift (8-12% opacity change)
   - Focus: crisp ring with accent color at 25-30% opacity
   - Active/Selected: 15-20% accent background
   - Transitions: 120-200ms for micro-interactions

   CODE ORGANIZATION
   - Modern CSS nesting for component encapsulation
   - Logical properties (inline/block) for i18n readiness
   - Custom properties for all design tokens
   - Minimal selector specificity

   ACCESSIBILITY
   - WCAG AA contrast ratios minimum
   - Focus-visible for keyboard navigation
   - Reduced motion respect via prefers-reduced-motion
   - Touch targets minimum 44x44px
