 ## 2. Folder Structure
 
-- `root/`: Application source code served by Apache.
+- `root/`: Application source code served by FrankenPHP/Caddy.
     - `index.php`: Single endpoint returning `REMOTE_ADDR` as JSON.
+- `Caddyfile`: FrankenPHP/Caddy web server configuration — PHP handler on `:8080` with `try_files` + `php_server`.
 - `.gitea/workflows/`: Gitea Actions CI pipelines.
     - `docker-build.yaml`: Build and push Docker image to Docker Hub on push/PR to master + daily cron.
-- `Dockerfile`: Multi-stage build extending `jcabillot/phpapache` base image, copies `root/` into `/var/www/html`.
+- `Dockerfile`: Single-stage build from `dunglas/frankenphp:1-php8.5-alpine`, copies `root/` into `/app/public`.
 - `.gitlab-ci.yml`: Legacy GitLab CI config (deprecated, replaced by Gitea Actions).
 - `Jenkinsfile`: Legacy Jenkins pipeline (deprecated, replaced by Gitea Actions).
 
 ## 3. Core Behaviors & Patterns
 
 - **Request/Response Flow**: Single PHP endpoint sets `Content-Type: application/json` header and returns `$_SERVER['REMOTE_ADDR']` encoded as JSON string. No routing, no framework, no state.
-- **Container Base Image Pattern**: `Dockerfile` uses `ARG VERSION="latest"` to allow version pinning at build time, extends `jcabillot/phpapache` which provides PHP + Apache pre-configured. Application code is layered on top via `COPY root /var/www/html`.
+- **Container Base Image Pattern**: `Dockerfile` is a single-stage build from a fixed `dunglas/frankenphp:1-php8.5-alpine` tag (Alpine-based FrankenPHP with Caddy). No `ARG VERSION` — the tag is pinned, Renovate auto-detects it. Application code is layered via `COPY root /app/public`. FrankenPHP provides PHP + Caddy pre-configured.
 - **Traefik IngressRoute with HTTPS Redirect**: Two IngressRoute resources handle traffic — `ip-websecure` serves HTTPS on the `websecure` entrypoint, `ip-web` catches HTTP on `web` entrypoint and applies a `redirectScheme` middleware for permanent HTTPS redirect. The Service reference in the HTTP IngressRoute is required by Traefik even though the middleware intercepts before reaching it.
 - **Health Probes**: Deployment defines both `livenessProbe` and `readinessProbe` using `httpGet` on `/` at the named `http` port (8080). Kubernetes uses these to restart unhealthy pods and exclude unready pods from the Service endpoints.
 - **Security Hardening**: Pod spec sets `automountServiceAccountToken: false` to prevent unnecessary Kubernetes API access from the container.
