Vectors must have same dimension

Error message

Vectors must have same dimension

What it means

Thrown by mobiusAdd when the two input vectors a and b have different lengths; Möbius addition in the Poincaré ball is only defined element-wise over vectors of identical dimension, so any dimension mismatch aborts before the curvature/epsilon math begins.

Solutions

1. Ensure both vectors come from the same embedding model before the operation.
2. Check this.dimensions against the input length and regenerate the shorter vector.
