   erkennen.css — page-scoped enhancements for the "Asbest erkennen" page
   ---------------------------------------------------------------------------
   Loaded ONLY by /asbest-erkennen/ and its language mirrors
   (/en/asbestos-identification/, /hu/azbeszt-felismeres/).

   It MUST NOT be referenced site-wide. The global design system lives in
   css/style.css; this file only adds the interactive/educational components
   built for this one page. Everything is namespaced under `.asbest-erkennen`
   (the <main> class) so a stray global include could never restyle other pages.

   Tokens mirror :root in css/style.css with literal fallbacks, so the page
   still renders correctly even if the cascade order changes.
