- Create Experience.tsx component with vertical timeline layout
- Add 5 roles from NHS and Tesco with bullet points
- ECG waveform SVG decoration beside heading
- Timeline dots filled for current roles
- Hover effects on cards (scale, shadow, left border)
- Scroll-triggered animations using useScrollReveal hook
- Responsive: hide timeline line/dots on mobile
- Fix useScrollReveal ref type for React 18+ compatibility
