   HILFE-CENTER — /hilfe and /hilfe/<slug> (src/lib/help.js)
   ==========================================================================
   After /legal.css, whose hero, layout and reading column the articles use.
   This file adds the help centre's own parts: the search, the category
   chips, the article cards, and the blocks inside an article (steps, notes,
   a menu path). The search filters the cards in place (js/pages.js).
   Prefix `hc-`.
