Details

Browse Source 
T0.1: Separate redis-auth service (64mb, noeviction) for auth state
T0.2: Bump data Redis from 256mb to 1gb
T0.3: Per-app DATABASE_URL via PgBouncer to per-domain databases
T0.4: PgBouncer service (transaction mode, pool=20, max_conn=300);
      session.py pools reduced to 3+5 with timeout and recycle
T0.5: Hypercorn --workers 2 --keep-alive 75 on all 6 entrypoints

Deploy requires running split-databases.sh first to create per-domain
databases from the existing appdb.
