cts: re-encodes the CTS tape at each CTS step via encode_cts_state and shows a scrolling window of bands around the current step — each band is an independent re-encode (state correspondence per step), not a causal continuation. Otherwise glider placements OR raw bitstring. Crossings ringed in yellow.
