# Tumbling Cube Preloader

> A looping cinematic preloader: a 3D typography cube tumbles your word one letter per face over a WebGL-graded plate (chromatic aberration, film grain, CRT scanlines), with a percentage counter underneath. Use it as a standalone looping loader, or as a page gate that lifts to reveal your content. No dependencies beyond React; falls back to a procedural film plate when no reel is supplied.
