No official figure published for: recommended RAM, recommended CPU cores

Docs give a minimum for <=200 users and a separate user-count-scaled table (500 users: 8 CPU/8GB; 1500 users: 16 CPU/16GB) instead of a single 'recommended' figure — publishing any one tier as 'recommended' would misrepresent a scaling guideline as a fixed target (Defect Class #2).

We publish nothing we can't source. Evidence of the gap.
