+- `STRATEGY_PROFILE`: set per service. The deployment control plane now also carries `RUNTIME_TARGET_JSON`; treat `STRATEGY_PROFILE` as a compatibility input that still selects the strategy implementation, not the only identity key.
 - Current strategy domain is `us_equity`. `STRATEGY_PROFILE` still goes through a platform capability matrix plus a rollout allowlist derived from `runtime_enabled` strategy metadata: `eligible` means the platform can run it in theory, `enabled` means the current rollout really allows it.
 - `ACCOUNT_REGION`: explicitly mark the deployed account region (`PAPER` / `HK` / `SG`); if unset, the app falls back to `ACCOUNT_PREFIX` or `DEFAULT`
