Declare maxReplicas activator 20->3, webhook 5->2, 3scale-kourier-gateway 10->3 and 10m CPU requests for all six substrate containers (220m->60m), per the resource-control node budget of 2026-10-21 (CUST-WP-0071, RESOURCE-WP-0008). Read-only BEFORE evidence under docs/evidence/2026-10-21-hpa-caps-before/. Not applied; railiance-cluster overlays must follow (handoff in T02).
