classColorOverLifetime

@codexo/exojs-particles / particles / stable

Per-frame, per-particle color sampler. Each live particle's tint is set to the gradient evaluated at the particle's current `elapsed / lifetime` ratio, packed RGBA. Replaces the per-particle blend of `ColorAffector` (legacy) with a multi-keyframe gradient. GPU-eligible: the gradient is uploaded once as a 256-tap 1D RGBA8 texture and sampled with linear filtering on the GPU.
