Per-pipeline READMEs cover everything specific to that pipeline (source schema, renderer, runtime, decisions). This root README covers only what's cross-cutting.
Hybrid layout. The Gitea Actions trigger must live in the source repo (Gitea only fires workflows from `.gitea/workflows/` of the pushed-to repo); the rendering logic lives here. The source-repo workflow is self-contained but clones this repo at runtime to get the renderer.
Note: `workflow_call` across private repos was abandoned — the auto-generated run token is scoped to the triggering repo only and cannot clone a private callee. The source-repo workflow clones this repo directly using `FAPAT`.
One `act_runner` instance serves all pipelines. Runs on a Pi 5 (Raspberry Pi OS Bookworm, `aarch64`) inside the same `docker-compose` stack that hosts the Gitea instance. Job execution is via the host Docker socket — runner is a container, jobs spawn as sibling containers.
`act_runner` build: `linux-arm64`, from the `gitea/act_runner` Docker image.
All pipelines share a single pre-built Docker image, served from the Gitea registry at `pi5-16.local:3005/mikkeli/novoyuuparosk-wiki-runner`. The `Dockerfile` is at the repo root. It bakes in system deps (git, pandoc, ca-certificates) and all pipeline Python packages so job containers start instantly with no install steps.
The image builds automatically via [`.gitea/workflows/build-image.yml`](.gitea/workflows/build-image.yml), which triggers on pushes that touch the `Dockerfile`, any pipeline `requirements.txt`, or that workflow itself. It uses kaniko (daemonless, unprivileged) to build and push two tags: an immutable `:<short-sha>` and a moving `:latest`.
A follow-up `pin` job then rewrites the `image:` pin in each `publish-*.yml` to the new `:<short-sha>` and commits it back to `master` (using `FAPAT` for contents write). The publish workflows therefore always reference an immutable tag, kept current automatically — no manual bump. The pin commit only touches `workflow_call` files, so it triggers no further runs.
-`URL_TO_GITEA` = Gitea instance base URL (e.g. `http://localhost:3005`). Named with `URL_TO_` prefix — Gitea blocks variable names starting with `GITEA_` or `GITHUB_`.

- [x] Add `act_runner` service to the existing Gitea docker-compose
- [x] Generate a runner registration token at `/-/admin/actions/runners`, bake into the compose env, `docker compose up -d act_runner`, confirm "online" in the Gitea UI
