Website: list the machine estimator — menu, sitemap, FAQ and apps-page links; R-997 closed

noindex and the robots Disallow lines removed; both URLs in the sitemap with their hreflang pair; the pair
moves from UNLISTED to TWINS in site_gates.py. The explaining sentence's base figure was already the drawn
box's base; a test now pins it (red-proved).

+- **Public now:** `noindex` removed from `/gepigeny` and `/en/sizing`; their `Disallow` lines removed from robots.txt;
+  both in sitemap.xml with their hreflang pair.
+- **Menu:** „Milyen gép kell?" / „Which machine do I need?" is the last item of the Alkalmazások / Apps group on every
+  page of each language (active and open on the estimator itself).
+- **Links:** one sentence at the end of the FAQ answer „Milyen gépre van szükségem?" / „What machine do I need?" (the
+  JSON-LD carries it too), and one line under the apps page intro („Mekkora gép kell ezekhez? →").
+- **The explaining sentence:** its base figure was already the base of the box the bar draws (4.0 GB on an 8 GB bar,
+  4.6 GB for the household preset); a test now pins that. No JS, CSS or data change, so no cache version moved.

 - **The bar is never drawn for a box smaller than 8 GB** (the smallest size the page names). With nothing or very
   little ticked, the „fits well" size was about 2.3 GB, where the installer's ceiling clause gave a 1.6 GB base
