{# Settings → Features (issue #62): real DB-row runtime toggles for the live-read
   capability flags. Each control is tri-state — On / Off / use the installation
   (env) setting (which writes NULL so an override never permanently pins). The
   POST validates the effective combination server-side through the shared
   validate_effective_flags and re-renders with a plain-language message on a
   violation, writing nothing. Self-contained: renders from _settings_context. #}
