Proximity Text turns a block of type into an interactive field. Characters near the pointer brighten, thicken and swell, falling off smoothly with distance and easing back as you move away.

The glow is purely typographic, no lighting, no shadows, no blur. A single proximity value per character drives three things at once: a color ramp, variable font weight, and scale. That's what gives it a depth a drop-shadow can't fake.
