 - `scripts/ops/docker-health-monitor.sh` 預設排除 `gitea-runner`，避免 Docker 自動修復把已停用 runner container 每 5 分鐘拉起。
 - `.gitea/workflows/cd.yaml` 拆為 `tests`、`build-and-deploy`、`post-deploy-checks` 三段；API/Web Docker build 與 GitOps deploy 改跑 `awoooi-host`，不再在 transient act job container 內長時間 build。
 - host deploy step 的 `kustomize` 改安裝到 `${HOME}/.local/bin`，避免 host runner 沒有 root 權限時寫 `/usr/local/bin` 失敗。
+- post-deploy Playwright smoke 在 browser cache 命中時也會檢查 OS shared libs，缺 `libnspr4.so` 等 Chromium 依賴時自動補 `install-deps`。
