A deliberate duplicate of @fourjs/render's PARTICLE_INSTANCE_FLOATS,
which is the normative definition. The dependency matrix forbids importing it
(see the module header), so the value is restated here, exported so a caller
can size or slice the array without guessing, and pinned by the tests on both
sides.
Floats per particle in ParticleRenderable.particleInstances: centre (3) + current size (1) + current straight-alpha RGBA (4).
