Documented selection limits

Configurable server platform: CPU, RAM, drives, GPUs, networking adapters and optional licenses are not asserted to be installed. All capacities are supported limits or configuration options, not delivered capacity. Agree the exact BOM separately. Multi-node counts and limits retain per-node versus shared-system scope. NVMe/SAS/SATA, risers, cooling and power redundancy may require specific optional hardware and workload validation. No stock or lifecycle guarantee.
