Neon Hex
Neon Hex
Move your cursor to illuminate the grid
```
This creates a fully interactive **Neon Hex** grid with:
- **Honeycomb hex grid** rendered on HTML5 Canvas with pointy-topped hexagons in a proper staggered layout
- **Mouse-reactive glow**: Hex cells near your cursor illuminate with layered neon glow (outer soft bloom → mid layer → bright outline → white-hot core)
- **Dynamic color cycling**: The palette smoothly transitions between 6 neon colors (cyan, magenta, purple, spring green, orange-red, blue)
- **Particle system**: Particles shoot from your cursor path with trails, physics (drag + slight gravity), glow effects, and bright white cores that fade out over time
- **Ambient pulsing**: Hex cells have subtle idle animations even without interaction
- **Performance optimized**: Particle cap at 600, skip drawing invisible hexes, efficient spatial checks
- **Responsive**: Full-screen canvas that resizes with the window
