pub fn window_embedding(w: &CsiWindow) -> Vec<f32>Expand description
Build the deterministic embedding for a CsiWindow.
The returned vector has length WINDOW_EMBEDDING_DIM; see that constant’s
docs for the exact bin layout. The result is L2-normalized (or all-zero for
an empty window — i.e. subcarrier_count == 0 and frame_count == 0).
