   ==== Task 10B: Pitaj pravilnik (AI chat) + floating "Pitaj" button ====
   js/views/pitaj.js, js/components/chat*.js, the .nz-askfab in index.html.
   Editorial, not a chat app: questions read like headings in a ledger,
   answers like prose with citation chips; one red accent (the send button).
