 Phase 16 ships the grzybyfunkcjonalne.pl FAQ (`g15_faq` slug `what-mushrooms-can-give-you`) as static i18n/markdown content in the Nuxt app. Later blogs need editors to manage FAQs, so port `Golem15.Faq` 1:1 as its own `sm-faq-plugin` repo (see `.planning/notes/core-plugins-own-repos.md`): models, admin screens and a public read API by slug.

 Phase 14 dropped sitemap for Płytarium, because Nuxt builds its own sitemap with `@nuxtjs/seo` and fonoteka registers no menu item types. The next port after Płytarium is a blog project (grzybyfunkcjonalne.pl or golem15.com), and it needs `Golem15.Sitemap` 1:1.

 Chromium now warns on `/sitemap.xml` (seen on UAT during the Phase 17 UAT, test 7): "This site uses XSLT; that functionality is being removed from this browser very soon…". The sitemap plugin serves the PHP plugin's `<?xml-stylesheet type="text/xsl" href=".../sitemap.xsl"?>` and `/sitemap.xsl` to show a readable table in the browser.
