-zachowując poprawność dla crawlerów.
+Domyślny `/sitemap.xml` (Next MetadataRoute) działa dla Google, ale w przeglądarce
+bywa nieczytelny. Możesz serwować go jako **czysty, sformatowany XML** przez
+`buildSitemapXml` — przeglądarka pokaże wbudowane drzewo XML (wcięcia, zwijanie,
+kolorowanie składni), bez żadnej transformacji.

-### Ograniczenie Next

-Standardowy `app/sitemap.ts` (Next MetadataRoute) **nie pozwala** wstrzyknąć

+> **NIE używaj XSLT.** Przeglądarki (Chrome i in.) WYCOFUJĄ XSLT — arkusz

+> Rozwiązanie: serwuj czysty XML z poprawnym Content-Type; przeglądarka
+> renderuje swój natywny widok drzewa XML sama.

-Jeśli używasz route `app/sitemap.xml/route.ts` (styled), **USUŃ** `app/sitemap.ts`

- **styled** (`sitemap.xml/route.ts` + buildSitemapXml + XSL) — ładna tabela
- **prosty** (`sitemap.ts` + reeksport z lib/content) — bez stylu, mniej kodu

- * staying a valid sitemap for crawlers.
+ * Serializes sitemap entries to a clean, indented XML STRING — valid for crawlers
+ * and readable in the browser as the native XML tree (indented, collapsible,
+ * syntax-highlighted by the browser itself).
 *
- * Why this exists alongside the Next MetadataRoute sitemap: Next's app/sitemap.ts
- * (returning SitemapEntry[]) does NOT let you inject <?xml-stylesheet?>. To get
- * the styled table, serve a custom route that returns this string instead:
+ * NO XSLT stylesheet: browsers (Chrome et al.) are REMOVING XSLT support, so a
+ * <?xml-stylesheet?> approach is a dead end — it shows a deprecation warning now
+ * and will break soon. Instead we serve plain XML with the correct Content-Type;
+ * the browser renders its built-in formatted XML view (the "code tree" look) with
+ * no transformation needed.
 *
 *   // app/sitemap.xml/route.ts
 *   import { buildSitemapXml } from '@intecion/ipal-kit'
- *   import { sitemap } from '@/lib/content'   // your entries source

 *
- * Put sitemap.xsl in the project's /public (copy from the plugin's assets, or
- * serve it from a route). The <?xml-stylesheet?> points browsers at it; crawlers
- * ignore it and read the XML. Include hreflang alternates as <xhtml:link>.
+ * The indentation makes the raw XML pleasant to read; the browser's default XML
+ * viewer adds the tree/fold UI. Crawlers read the XML as usual.
 *
 * NOTE: if you use this custom route, DON'T also keep app/sitemap.ts — pick one
- * (the styled route OR the Next MetadataRoute). Two sitemaps at different paths
- * confuse crawlers.
