Sign Customiser’s Flow RGB effect now produces a beautiful, realistic neon glow that flows across your entire sign. Each word is lit with a smooth colour gradient that shifts naturally based on its position, creating the appearance of real RGB LED tubing cycling through colours in sequence.

## What’s Changed

- **Multi-layer neon glow**Four glow layers create a rich, realistic neon tube appearance with soft light falloff that closely mimics real RGB LED signage
- **Spatial gradient animation**Colours flow smoothly across words based on their position on the canvas, so multi-word signs display a natural colour wave rather than each word changing independently
- **Optimised for all devices**Frame throttling and reduced glow layers ensure smooth performance on mobile devices and Safari, without sacrificing visual quality
- **White face with coloured glow**The text itself remains crisp white while the surrounding glow cycles through your chosen RGB colours, just like real neon tubing

No action is needed on your end — this effect applies automatically to any customiser that already uses the Flow RGB colour effect.
