Move the guide to its own domain twojajdg.pl

The site lived at sobolevbel.github.io/jdg/, where Google derived the site
name from the host's home page (GitHub's 404) instead of the guide.

- docs/CNAME (not the repo root: gh-deploy --force rewrites gh-pages, so a
  root-level CNAME would be wiped on every deploy and unset the domain)
- site_url, extra.homepage, the sitemap line in docs/robots.txt and the five
  absolute in-content links now point at the apex
- overrides/main.html builds hreflang x-default from config.site_url instead
  of the hardcoded '/jdg/en/' path, which no longer occurs in canonical URLs
  (it would have left the EN URL untouched and pointed x-default at /en/)
- GA cookie_domain matches the new host, otherwise nothing is tracked
- lychee skips own-domain links: they only resolve after a deploy

+## Custom domain
+
+`twojajdg.pl` is an apex custom domain (registrar + DNS: OVH), live since
+August 2026. The `CNAME` file lives in **`docs/`**, not the repo root — CI
+deploys with `mkdocs gh-deploy --force`, which rewrites the whole `gh-pages`
+branch, so a root-level CNAME would be wiped on every deploy and GitHub would
+unset the domain. Apex needs four A records to `185.199.108–111.153` (plus AAAA
+`2606:50c0:8000–8003::153`); `www` is a CNAME to `sobolevbel.github.io`.
+GitHub then 301-redirects both `sobolevbel.github.io/jdg/` and `www` to the
+apex — that redirect is why every absolute URL (`site_url`, `extra.homepage`,
+the sitemap line in `docs/robots.txt`, in-content links) must point at
+`https://twojajdg.pl/` and never at the old github.io path. Own-domain links
+are excluded in `lychee.toml`: they only resolve after a deploy, and CI checks
+the PR before it. GA (`G-65Z83YVGT1`) pins `cookie_domain` in
+`docs/javascript/extra.js` — it must match the live host or nothing is tracked.

 ## August 2026
 
+- The guide moved to its own domain — `twojajdg.pl`. The old `sobolevbel.github.io/jdg/…` addresses redirect to the new ones automatically, so existing bookmarks and links shared in chats keep working.
 - Updated the [VAT-UE registration step in CEIDG](registration_vat_ue.md#13-registering-as-a-vat-ue-taxpayer): the goods/services checkboxes are gone from the form — now you only enter the expected start date of intra-community transactions (screenshot refreshed).
 - New page: [Full-Service Accounting](accounting.md) — when it makes sense to delegate the books, the terms of the guide's partner Legal Tax Level, and an honest section on alternatives.
 - The [Profil Zaufany](pz.md) page expanded: what you need it for, how to log in (including when the profile was created through a bank and there is no password), how to reset the password and extend its validity.
