Primary was at 401Mi / 512Mi (78%) before the first bump; the plan's 1Gi
leaves enough headroom for normal operation but thin margin if blocklists or
cache grow. User escalated: OOM cascades are the exact failure mode that
causes user-visible DNS outages, so give a full 2x safety margin across all
three instances. Replicas currently use 124-155Mi steady-state so they have
enormous headroom at 2Gi — accepted for symmetry and future growth (OISD
blocklists, in-memory cache).
