Custom domain stuck: apex NODATA, www resolves to third-party IP (Hostinger)

Site: lealoralclinic (b511ae24-407d-4f03-9039-707565fc2d3f). Custom domain lealoralclinic.com is state: ready with SSL issued, DNS zone contains only 2 clean NETLIFY-type records (apex + www) pointing to lealoralclinic.netlify.app. However, live queries against dns1.p08.nsone.net directly show: apex returns NODATA, www resolves to 54.232.119.62 (a third-party/Hostinger IP, not ours) with TTL 120s — persisting for 90+ minutes across Google/Cloudflare/Quad9 resolvers. Already removed duplicate DNS records that existed earlier. Need backend investigation into the NS1 zone for this domain.
