Demo: Fluid Luminescence
=========================

The **Fluid Luminescence** preset highlights real-time interaction between fluid simulation domains and reactive display surfaces.

Overview & Architecture
-----------------------

* **Liquid Domain Cascade**: Fluid splashes down a stepped glass architectural staircase.
* **Volume Sensing**: The glass steps act as display targets using **Thickness / Depth Only** and **Inverse Square** falloff modes.
* **Bioluminescent Glow**: As splashing liquid contacts and fills each glass reservoir, the display detects volume penetration and radiates intense cyan bioluminescent light through the fluid body.
* **Dynamic Refraction**: Combines real Cycles/EEVEE glass transmission materials with internal reactive emission.
