Migrate WordPress site to Hugo

Replaces the WordPress 7.0.2 / HitMag site with a static Hugo build,
deployed by Gitea Actions over rsync/SSH.

Content: 26 files (9 pages + 17 posts) as Markdown page bundles, plus
127 of 165 media attachments. The remaining 38 are media-library
leftovers that appear nowhere on the live site; they are listed in
MIGRATION.md.

The WXR export contains neither media binaries nor widgets, so both were
recovered from the live host before it is retired:
  - tools/fetch_media.py downloads all uploads, capping them at 2000px
  - tools/build_data.py scrapes the "Unsere Mitglieder" and
    "In Erinnerung" widgets into data/*.yaml

TablePress' six Termine tables became data/termine.yaml, rendered with
the newest year expanded and earlier years collapsed. Old permalinks are
not preserved (clean slugs, no redirects, as agreed).

Custom layouts, no third-party theme. Plain CSS, since the pinned Hugo
0.164.0 is the non-extended build and cannot compile Sass.

Verified: clean build with zero warnings, 718 internal links checked and
none broken, no surviving wp-content URLs.

+# motorradclub-giebelwald.de
+
+Static website of the Motorradclub Giebelwald e.V., built with [Hugo](https://gohugo.io).
+
+- Development: <https://mcg.luxick.de>
+- Production: <https://motorradclub-giebelwald.de>
+
+Migrated from WordPress in July 2026 — see [MIGRATION.md](MIGRATION.md).
+
+## Requirements
+
+Hugo **0.164.0**. The *non-extended* build is sufficient: the site uses plain CSS,
+no Sass.
+
+## Local development
+
+```sh
+hugo server -D      # http://localhost:1313
+hugo --gc --minify  # production build into public/
+```
+
+## Editing content
+
+Everything lives in Markdown under `content/`, edited via git (locally or in
+Gitea's web editor).
+
+### Add a news post
+
+Create `content/aktuelles/<slug>/index.md`:
+
+```markdown
+---
+title: "30. O-Fahrt 2027"
+date: 2027-01-15T10:00:00Z
+tags: ["O-Fahrt"]
+featured: "titelbild.jpg"
+---
+
+Text …
+
+{{< gallery "bild1.jpg" "bild2.jpg" >}}
+```
+
+Drop the images into the same folder. `featured` picks the teaser image; without
+it the first image in the folder is used.
+
+### Add or change a Termin
+
+Edit `data/termine.yaml`. Newest year is shown expanded, older years collapse:
+
+```yaml
+"2027":
+  - date: "06.02.2027\n18:30"
+    description: "Jahreshauptversammlung\nSängerheim Niederndorf"
+```
+
+### Members / In Erinnerung
+
+`data/members.yaml` and `data/memoriam.yaml`. Images go in `assets/img/`.
+
+### Downloads
+
+Put the PDF in `static/dokumente/` and link it from `content/downloads.md`:
+
+```markdown
+{{< pdf "satzung.pdf" "Unsere Satzung" >}}
+```
+
+## Shortcodes
+
+| Shortcode | Purpose |
+|---|---|
+| `{{< gallery "a.jpg" "b.jpg" >}}` | Thumbnail grid; no arguments = all images in the bundle |
+| `{{< figure "bild.jpg" "Bildunterschrift" >}}` | Single image with caption |
+| `{{< pdf "datei.pdf" "Titel" >}}` | Download link with file size |
+
+## Deployment
+
+`.gitea/workflows/deploy.yml` builds with Hugo and rsyncs `public/` over SSH.
+
+- Push to `main` → deploys to **mcg.luxick.de**
+- Manual *Run workflow* with `environment: production` → deploys to
+  **motorradclub-giebelwald.de**
+- Pull requests are built but never published
+
+### Required secrets
+
+Set these in the Gitea repository settings:
+
+| Secret | Example |
+|---|---|
+| `SSH_PRIVATE_KEY` | Deploy key with write access to the webroot |
+| `SSH_KNOWN_HOSTS` | Output of `ssh-keyscan <host>` |
+| `DEPLOY_HOST` | `server.example.de` |
+| `DEPLOY_USER` | `www-deploy` |
+| `DEPLOY_PATH_DEV` | `/var/www/mcg-dev` |
+| `DEPLOY_PATH_PROD` | `/var/www/mcg` |
+
+rsync runs with `--delete`, so each `DEPLOY_PATH_*` must point at a directory
+owned solely by this site. The workflow refuses to deploy if the path is unset,
+too shallow, or if the build produced no `index.html`.
+
+## Migration tooling
+
+`tools/` holds the one-shot WordPress importer, kept so the import stays
+reproducible and reviewable. It is not part of the build.
+
+```sh
+python tools/fetch_media.py       # download uploads from the live WP host
+python tools/build_data.py        # termine / members / memoriam
+python tools/wp2hugo.py           # content bundles (won't overwrite; --force to do so)
+python tools/verify_migration.py  # inventory + link checks (run after `hugo`)
+```
+
+Requires Python 3.11+ and Pillow.
