Proven by theme switching and custom theme load.

+# S06: Docker + CI/CD
+
+**Goal:** Package the complete application into a production Docker image, create docker-compose configs for zero-config and secure deployment, and set up GitHub Actions CI/CD for lint/test on PR and build/push on tag.
+**Demo:** `docker compose up` → app works at :8080 with zero config. Tag v0.1.0 → GitHub Actions builds multi-arch image → pushes to GHCR. PR triggers lint + test.
+
+## Must-Haves
+
+- Multi-stage Dockerfile: build frontend, install backend deps, minimal runtime image
+- docker-compose.yml for zero-config startup
+- docker-compose.example.yml with reverse proxy (Caddy) for TLS
+- GitHub Actions: CI workflow (PR: lint + test), Release workflow (tag: build + push)
+- Multi-arch support: amd64 + arm64
+- Health check in Docker and compose
+- Zero outbound telemetry verification
+
+## Proof Level
+
+- This slice proves: operational + final-assembly
+- Real runtime required: yes (Docker build + run)
+- Human/UAT required: yes (verify full flow in container)
+
+## Verification
+
+- `docker build -t media-rip .` — image builds successfully
+- `docker compose up -d && curl localhost:8080/api/health` — returns healthy
+- GitHub Actions workflow files pass `actionlint` (if available)
+- Zero telemetry: container makes no outbound requests
+
+## Tasks
+
+- [x] **T01: Dockerfile + .dockerignore** `est:30m`
+  - Why: The core deliverable — package everything into a production image.
+  - Files: `Dockerfile`, `.dockerignore`
+  - Do: Multi-stage build: (1) Node stage builds frontend, (2) Python stage installs backend deps, (3) Runtime stage copies built assets + installed packages. Use python:3.12-slim as base. Install yt-dlp + ffmpeg. Configure uvicorn entrypoint. Add HEALTHCHECK instruction.
+  - Verify: `docker build -t media-rip .` succeeds
+  - Done when: Image builds, contains frontend dist + backend + yt-dlp + ffmpeg
+
+- [x] **T02: Docker Compose configs** `est:20m`
+  - Why: Zero-config startup and secure deployment example.
+  - Files: `docker-compose.yml`, `docker-compose.example.yml`
+  - Do: Basic compose: single service, port 8080, /downloads and /themes volumes. Example compose: add Caddy sidecar with auto-TLS, admin enabled. Add .env.example with documented variables.
+  - Verify: Compose file valid (docker compose config)
+  - Done when: Both compose files parse correctly, volumes and ports mapped
+
+- [x] **T03: GitHub Actions CI workflow** `est:20m`
+  - Why: Automated quality gates on every PR.
+  - Files: `.github/workflows/ci.yml`
+  - Do: Trigger on PR to main. Jobs: backend lint (ruff) + test (pytest), frontend lint (vue-tsc) + test (vitest) + build. Use matrix for parallel execution. Cache pip and npm.
+  - Verify: Workflow YAML is valid
+  - Done when: CI workflow covers lint + test + build for both stacks
+
+- [x] **T04: GitHub Actions Release workflow** `est:20m`
+  - Why: Tag-triggered build and push to container registries.
+  - Files: `.github/workflows/release.yml`
+  - Do: Trigger on tag v*. Build multi-arch (amd64, arm64) via docker buildx. Push to GHCR. Create GitHub Release with auto-generated notes. Cache Docker layers.
+  - Verify: Workflow YAML is valid
+  - Done when: Release workflow builds and pushes on tag
+
+- [x] **T05: Final integration + docs** `est:20m`
+  - Why: Verify everything works end-to-end and document for operators.
+  - Files: `README.md`
+  - Do: Write README with quickstart, configuration, theme customization, admin setup, deployment. Verify Docker build. Run full test suites one final time.
+  - Verify: All tests pass, Docker builds, README is complete
+  - Done when: Project is ship-ready with documentation
+

+# S06: Docker + CI/CD — Summary
+
+**Delivered production Docker image, zero-config and secure compose configs, CI/CD GitHub Actions, SPA static serving, and full README documentation. 211 total tests pass across backend and frontend.**
+
+## What Was Built
+
+### Dockerfile (T01)
+- Multi-stage build: Node 20 (frontend build) → Python 3.12 (pip install) → python:3.12-slim (runtime)
+- Runtime includes: ffmpeg, curl, yt-dlp (latest stable)
+- HEALTHCHECK instruction using `/api/health`
+- OCI labels for image metadata
+- Volumes: /downloads, /themes, /data
+- Environment defaults for all config via MEDIARIP__ prefix
+
+### Docker Compose (T02)
+- `docker-compose.yml`: zero-config, single service, port 8080:8000
+- `docker-compose.example.yml`: Caddy sidecar with auto-TLS for production
+- `Caddyfile`: simple reverse proxy config
+- `.env.example`: documented environment variables
+
+### CI Workflow (T03)
+- Triggers on PR and push to main/master
+- Parallel jobs: backend (ruff lint + pytest), frontend (vue-tsc + vitest + build)
+- Docker smoke test: build image, run, curl health endpoint
+- pip + npm caching for fast CI
+
+### Release Workflow (T04)
