/* ==========================================================================
   ANIMATIONS & MICRO-INTERACTIONS
   Adhering to Emil Kowalski motion principles & DESIGN.md guidelines:
   - Only transform and opacity (GPU accelerated)
   - Snappy durations (150ms-250ms for UI, 500ms-700ms for springs)
   - Calibrated bezier curves
   - Reduced-motion accessibility overrides
