Gandi LiveDNS rejects the RFC-7505 null-MX value '0 .' ('invalid format for MX
record'), which failed the live apply. No MX + no apex A = no mail delivery, and
SPF -all + DMARC reject still prevent spoofing — so remove Gandi's seeded MX (add
@/MX to absent) rather than declare a null-MX present. Assert now requires an SPF
@/TXT record; tests + Molecule sample updated.
