audit: M3 STOP 2 - the page table and what was checked on all 19

Records the three faults that measurement found and looking would not have:
168 words silently deleted by the first page-header transform, the contact pages'
header sliding under the sidebar (content column at x=642 instead of 240), and two
pages that already scrolled sideways on a phone BEFORE M3.

Also raises the one thing needing an operator decision: the English home page is
the old design in the new frame, because the /preview/ round never produced an
English twin. 4 186px tall in Hungarian, 10 786px in English.

+# M3 — every page in the shell (STOP 2)
+
+**19 pages, all staged under `/preview/m3/`, nothing live.** `noindex`, blocked by `robots.txt`, in
+no sitemap, linked from no live page. `felhom-controller` was read only throughout.
+
+## The pages
+
+The sidebar's own links point at the preview copies, so you can click straight through the whole
+site. At the switch they are regenerated pointing at the real URLs (one flag, then a check that no
+`/preview/` string survives).

+
+| Check | Result |
+|---|---|
+| HTTP status | 19 × 200 |
+| **Visible text vs the live page** | **identical on all 19**, word for word, after the one allowed dash substitution |
+| **Legal texts** (`adatkezeles`, `feltetelek`) | **identical with NO substitution permitted at all** — 1 396 and 608 words |
+| Horizontal overflow at 390 px | none on any page |
+| Content column at 1440 px | starts at x=240 with the full 1 185 px on all 19 |
+| Sidebar identical across pages | gate 3b: 11 Hungarian, 8 English, all identical |
+| FAQ structured data == visible answers | gate 17 green on both `gyik` and `en/faq` |
+| `<head>` (title, description, canonical, hreflang, OG, JSON-LD) | carried over byte-for-byte; only `shell.css` and the no-js hook added |
+| Sidebar button on one line | all 19 |
+| Em dashes replaced | 318 across 16 pages (`gyik` and `en/faq` 104 each) |
+
+## Three faults found by measuring, not by looking
+
+1. **168 words silently deleted.** The first page-header transform rebuilt the block from its `<h1>`
+   and first `<p>` and dropped everything else — the „Fontos tudnivalók" / „Good to know" disclaimer
+   on both apps pages, and the 404's English line. The pages looked perfectly fine. The word-level
+   diff caught it; nothing else would have.
+2. **The contact pages' header slid under the sidebar.** `kapcsolat` and `en/contact` keep their
+   header outside `<main>`; left there it became a flex sibling of the sidebar, took 401 px and
+   pushed the content column from x=240 to x=642, rendering the form at two-thirds width. Now
+   anything before `<main>` moves inside it, checked structurally on all 19.
+3. **Two pages already scrolled sideways on a phone, before M3** — `/letoltes` (a 64-character
+   SHA-256) and `/adatkezeles` (a long legal URL), 609 px and 478 px at a 390 px viewport, on the
+   **live** site. Fixed with `overflow-wrap`, which also repairs the live pages today.
+
+## One thing that needs your decision
+
+**The English home page is the old design in the new frame.** Every other page is a faithful
+re-frame of its live counterpart, which is exactly what was asked. But the Hungarian home page was
+rebuilt from the `/preview/` round, and that round never produced an English twin — so `/en/`
+carries its old structure inside the shell. Measured: the Hungarian home is 4 186 px tall on a
+desktop, the English one 10 786 px.
+
+Nothing is wrong or untrue on it, and the twin gate passes. But the two home pages will look
+different to anyone who switches language. Options at the switch: ship as is and mirror it in a
+follow-up, or mirror it first.
+
+## Still deliberately not done
+
+- **The cross-repo gate** that would force the website's `shell.css` to keep step with the
+  controller. `design-system.md` §Shell records how a change flows; the brief says do not build the
+  gate yet.
+- **The controller's own two contrast defects** (`.btn-primary` 4.01:1 and `.nav-group-label`
+  3.14:1 on its own screen). Fixed for the website; the controller is read-only this session.
