/* ══════════════════════════════════════════════════════════════
   Keln — Support and FAQ.

   These pages get the same material as the sidebar and the dossier.
   A support page that looks like an afterthought tells someone
   exactly how much their problem matters, and it is often the
   second page a frustrated user sees.

   Shared by faq.html and support.html so the two cannot drift.
