Subject: [PATCH] IX: Phase 2 done (30 sites -> FPM/OPcache) + FPM default for
 new accounts

20 remaining ea-php suPHP candidates flipped to FPM + all 10 alt-php84 Selector sites
reset native -> ea-php84 FPM. 30/30 OK, bodies clean, zero rollbacks (biggest: cryoweave
13.5s->0.87s, drsticken 9.1s->0.29s). Four flat-looking one-shot samples re-verified faster
at steady-state. Set default_accounts_to_fpm=1 so new accounts provision on FPM. 41 sites
now on FPM/OPcache; ~31 fast-but-cold remain (Phase 3, optional).

 - **hightechmortgage.com 500: RESOLVED (2026-07-20)** — root cause was PHP OOM (`memory_limit` 128M exhausted

   returns 200, no new fatals. Will move to FPM in Phase 2 (memory_limit carries over).
