/**
 * posts.css – Funktionales Basis-Styling fuer Beitrags-Extensions.
 *
 * Nur JS-generierte Elemente (Filter, Pagination, Loading, Error, Ansichts-Toggle).
 * Template-Inhalte (z.B. blog-card, news-teaser) werden NICHT gestylt –
 * das macht die Website-eigene style.css.
 *
 * Alle Klassen nutzen das Prefix .xeno-posts- um Konflikte zu vermeiden.
 * Website-Designer ueberschreibt alles per eigener CSS-Datei.
 *
 * Zusammenhaenge:
 *   - posts.js → Erzeugt die HTML-Elemente fuer Filter, Pagination, Loading etc.
 *   - class_website_parser.php → Rendert posts-list/posts-detail Extensions
