ISO 1.29.0 source + an English download page (R-559 slice 4, source only)

THE IMAGE IS NOT BUILT AND NOT PUBLISHED BY THIS COMMIT. Publishing to
iso.felhom.eu is public and irreversible and its runbook requires a proof
install on BOTH menu entries plus the 16-criterion gate run against the exact
uploaded bytes. That is the operator's step. The download pages therefore still
name 1.28.0 - the image that is actually published - and a new site gate
refuses the two pages naming different files or hashes.

Three texts a person meets before any dashboard become bilingual: Hungarian
block first, byte for byte as before, then English, inside the same frame. The
pairing banner, the bound banner, /etc/issue (and the postinst's byte-coupled
copy), plus an English half on the GRUB entries.

The Hungarian is a GOLDEN, not a grep: test/golden/*.hu.txt were captured from
the script at 183727db9c before one English line existed, and the harness
asserts each banner's first N lines are exactly the golden. Red-proofed by one
changed byte, by an "a" planted in the English block, and by an over-wide line.

R-586, found on the way in: running the harness UNCHANGED at the base commit
failed two R-496 checks. The script paints with `>`, which truncates a FILE but
is a no-op on a console device; ISO 1.28.0's new bound banner (c033b3b) paints
straight after the pairing one and wiped it before the check read it. c033b3b
did not touch the harness, and nobody saw it because the harness is in no gate
and no CI run. Fixed with a FIFO; production code untouched. The harness being
ungated is still open.

The release gate's G16 required every Felhom string to be Hungarian and would
have STOPPED this publication. Operator ruling 1b of 2026-09-17 supersedes that
scope, so G16 is rewritten rather than waived: Hungarian FIRST, pinned by the
golden, each secret named once per language.

letoltes.html changes by four lines only. The English link is not in the nav -
the nav is a shared block site_gates.py pins across every page, and the gate
convicted the first attempt.

+## 2026-09-18 — an English download page (R-559)
+
+- **`website/en/download.html`** — the English twin of `letoltes.html`. Same installer, same checksum,
+  same structure; `<html lang="en">`, its own English nav and footer, `hreflang` alternates both ways
+  (`x-default` points at the Hungarian), and an entry in `sitemap.xml`.
+- **`letoltes.html` changed by FOUR lines and nothing else**: three `hreflang` alternates and one
+  `English` link in the page header. The link is deliberately **not** in the nav — the nav is a shared
+  block that `site_gates.py` pins across every page, and the gate convicted the first attempt, which
+  is how the link found its right home.
+- **The rest of the marketing site stays Hungarian** (operator ruling 1b, 2026-09-17).
+- **New gate 12: the two download pages must name the SAME installer file and the SAME checksum.**
+  Publishing an ISO now means editing a filename, a size and a 64-character hash on two pages; update
+  one and forget the other and an English reader checks a new image against an old hash, fails, and is
+  told by the page itself not to use the file. Red-proofed both ways.
+- `en/download.html` is registered in `PAGES` and in the new `EN_PAGES` set, which exempts it from the
+  Hungarian nav/footer comparison and from nothing else.
+
+**Published:** the site's normal path — push to `main`, git-sync picks it up in ~1–2 min. No
+`site.css` change, so no cache-bust bump was needed.
