Orange stains in Diaper + Rust colour urine

FTM here and my baby is 7 days old. He has slight jaundice.

2 days back we saw some orange stains in his diaper and today his urine colour has been rustic/orange in colour since last 2 diaper change.

Perplexity says this is normal urate crystals which is there in new borns but not sure.

Just FYI - He is exclusively BF with 8-10 wet diapers as of now.
