A cocktail glass, liquid and all, in three.js

Ann Nguyen asked Opus 5.5 for cocktail-glass effects in three.js, and the reaction is the sound of a test being passed: it actually delivered, and the effect looks good.

A glass is a solved object. Transparency, a rim, a highlight. Liquid is where browser graphics still look like a trick: the surface has to move, the refraction has to agree with the glass, and the drink has to seem to have a volume rather than a texture stretched over a blob.

Sixteen seconds, no speech, one object. The assignment was small enough that there is nowhere for a weak effect to hide.
