zero-padding vectors changes neither dot products nor norms — every PAIRWISE cosine within one homogeneous vector space. Tension: you never mix it with another provider's vectors in the same index, because cross-space cosines are meaningless. Outcome: a 384-dim local model zero-padded to 1536 behaves identically to running it at native dims.
