Each node chunk now carries its own region field, assigned round-robin across the full provider region list unless the user pinned a specific region. AWS uses the same async/poll:0 pattern as Linode but with a serial per-unique-region setup phase (key import + SG) before firing all creates in parallel. Teardown uses hostvars ec2_region per node so multi-region AWS teardowns hit the right endpoint. Infisical replaces interactive credential prompts for both providers. Linode vars.yaml instance type corrected to g6-nanode-1.
