/* BUNKM — the FAQ chat: dialog and corner button (shared by every page).

   14.10.2026 — until today the chat lived in bunkm.css and in index.html only, so it existed on
   one page. This file is the one place for its look; bunkm-chat-seite.js builds the markup.

   It carries its own colours (the --bk-* values below) and its own reset, because the pages do
   not agree: bunkm.css names the paper --paper-solid, help-pages.css names it --paper, the text
   pages have neither — and help-pages.css resets `* { margin: 0 }`, which takes the browser's
   centring away from a modal dialog (the same slip as 02.10.2026, see bunkm.css `dialog`). */
