/**
 * Account-local security baseline for org MEMBER accounts (first tenant:
 * seahaven-external-dev). Absorbed from the retired seahaven-external-dev-baseline
 * repo — a stripped fork of the management-account baseline, now sharing its
 * constructs (prefix-parameterized) instead of forking them.
 *
 * Deliberately excludes everything that is org-level or prod-specific:
 *   - No local CloudTrail — the management-account org trail (seahaven-org-trail)
 *     already captures every member account's events centrally.
 *   - No CIS Section-4 metric-filter alarms — the Security Hub CIS standard
 *     evaluates those controls against Config without a local trail log group.
 *   - No WAF, SES monitoring, Bedrock logging, DynamoDB CMK, or AWS Backup —
 *     all prod-only concerns.
 *
 * Contains: AWS Config, GuardDuty, Security Hub (FSBP + CIS v3.0), IAM Access
 * Analyzer, Inspector2 (post-deploy CLI, see README), VPC flow logs, and a
 * monthly cost Budget.
